title: lampp not working with i3 window manager

text: I am running Ubuntu 12.04 LTS. I installed the i3 window manager and have become pretty comfortable with it. And yesterday, When I tried to use Lampp for web dev, it didn't work. The window manager was the last thing on my mind, and thus I created a new file and tried to access it, but nothing really worked. Then, as a longshot, I logged out and logged in again into a Gnome session, and it worked! Thus, lampp is not working with the i3 window manager. I got the error `ERR_EMPTY_RESPONSE` when I tried to access a project stored in the directory `/opt/lampp/htdocs/` (just to give background, I am a power user and have used Lampp for a long time now and have never faced this problem, and it's not a problem with the setup, as I have already checked all the settings and the exact settings are working in the Gnome session). The following commands are the ones that I used.   1. `sudo /opt/lampp/lampp start`   2. `sudo chmod 777 -R /opt/lampp/htdocs/` (Ensuring that access denied error is not thrown by the browser)

title: How to reassign new values to array elements?

text: I'm trying to figure out like three or four things at the same time.The most I need help with is how to get the greatest number in all the files that I have created on a prior run of my script, that created a new file with a (int) identifier. to separate all of the files that have no metadata, to single them out to keep all of them from being over written because as I'm storing them all in the same folder. One is now to I be sure that I am getting the correct value in the element, I'm only using one element, the first one [0] to update the file by incrementing it in order from 0 ..... infinity. The incrementing I figured out using.               (( array[0]++ ))      the part that confuses me the most is the syntax and how I have its value changed by the computer and not me manually. I need to figure out how to get the biggest number that was put in the last file the script stopped at when making them, then have it beginning that number+1 when I start it up again so that it does not start all over again with the value of zero only to over write the other files it created the last time I ran it. As one should know the value goes away when I shut the computer off which loses the variables value. instead of going in the file and looking just get a script to do it for me. this is what I have so far to try and figure out how to get the greatest number. it is the how do I be sure that I am writing it correctly for it to get that new number inside of the [0] element to start with the last number I left off at plus one?               #!/bin/bash          typeset -i xf mf sn bn hn n  snewnum d          let xf=1 mf=0 bn=3 hn=4 n=1 snewnum=0          #to keep track of which lost-song file number I am on     n=0 bn=3 hn=4     lostsongs[0]=2          ###################################################     #     # FOR updating the lost song files so as not to      # over write any     ####################################     find /home/userx/testscripts/ -type f -name "*.mp3" | while [[ $n -le 4 ]] ; do      read FILE;     nstring=${FILE##*/} #gets just the file name     lstring=${nstring##I*"("} #chops off Lside to the ( leaving num     rstring=${lstring%%")"*} #chops off Rside to the ) leaving the num          snewnum=$rstring #holds the char of type num      echo $snewnum " new num before if"          lostsongs[n]="$snewnum"          echo "lostsongs[$n] = ${lostsongs[n]}"          echo ${#lostsongs[@]} " lostsongs length "          for(( a=0; a<${#lostsongs[@]}-1 ;a++ ));          do             store=0;                  if [[ lostsongs[a+1]<lostsongs[a] ]]; then                      store=lostsongs[a];                 lostsongs[a]=$lostsongs[a+1];                 lostsongs[a+1]=$store;                 echo "$store  in a"             fi                   done                    let n++     done      The bigger problem I'm having to figure out, how to pass variables all over the script to everywhere I need it to go. As I need to get the old array[0] with the new value inside of it to the proper place to use it. Within a completely different while loop.               find ~/music/ -type f -name "*.mp3" | while [ $xf  -le 150  ] ;        do read FILENAME;        ...............................     if [[ ! -n "$newArt" && ! -n "$newTit" && ! -n "$newAlb" ]] ; then          echo "${lostsogns[0]} that is Lsogn num.. before going to sogn"     newFile="I_HAVE_NO_IDEA-WHO-I-AM-(Lost-Song-Number-("${lostsongs[0]}"))-192k.mp3"     (( lostsongs[0]++ ))     let hn++      ...............      So I'd say my two major questions are how do I correctly write a re-assigning of an int value using a variable with a value inside of it into the array [ element ] other then incrementing or de-incrementing it by using the ++ or -- , and how do I pass it all around the script? why can't I seem to get               array[0]=$newvalue       to work? Everything I've read always has this really big complected looking "what are they doing?" that is not even close to what I want to do examples that do nothing but confuse me more. I find it hard to fine the simple examples for me to learn from then grow from there in my programming.


title: Determining a CD-R(W)'s capacity

text: I've seen various questions asked (and answered) regarding how to detect the size of various media on a GNU/Linux system, and in particular how much space has been used on an optical drive. But is there anything I can do to detect the _capacity_ of a CD-R(W) (i.e. is it a 650 / 700 / ... MB CD-RW)? I suspect that `cdrecord` / `wodim` is able to detect that before it even attempts to burn an ISO, but so far I haven't been able to use it to obtain the information I want. **EDIT** : I intend to use this information in a script I'm writing, so I'm only interested in command line tools (whose output I would parse). I'd also prefer a solution based on tools that are available by default on most systems.

title: Recover the content of a Firefox .part file?

text: The question says it all, I have a `<filename>.zip.part` file in my Firefox download directory which is ~150MB and I'd like to recover its content. The original file was a very large zip archive made of pictures and unfortunately it is now lost forever, so before redoing all the pictures again (illustrations for a book) I'd like to at least recover those that I already have in the .part file. I tried to open it with software like Ark but without success. Is there some trick to recover some of the file content? **Edit:** I managed to recover some files using a Windows software called ZipRepair Pro. While searching, I saw there are many similar Windows software. So another way to put the original question would be: is there a similar software for Linux?


title: How to configure my enviorment in such a way that a proper (different from the system one) version of library is used

text: I guess that this question is a borderline between ServerFault and StackOverflow and this site. But I think that U&L is most relevant. I have some `C++` code that depends on a library in version `X` and system provides version `Y` (X>Y). I have compiled this library and placed resulting files into `/opt/lib_name/X/lib`, version `Y` is installed in `/usr/lib64`. I want to link against `so` libraries. Now I'd like to create some script that somehow enables version `X`, so any code I build with `gcc` is compiled against version `X` without any changes in the makefiles. For now I set `LIBRARY_NAME_DIR` variable and in the makefile i just append `-L $LIBRARY_NAME_DIR`, which works but requires me to change makefiles. Is there any way to do to do this sort of things without having root access to the computer. Note: while I believe that answer to this question does not depend on the specific libary or the code, all details for my particular problem are here: http://stackoverflow.com/q/24189130/7918. What I have tried:   * I have set: `LIBRARY_PATH`, `LD_LIBRARY_PATH`, `CPLUS_INCLUDE_PATH`.


title: tar: how can I exclude intermediate directories but include leaf directories?

text: I want to create a tar file suitable for extracting into `/`. I've created a work directory that represents the root of the file system, and it has all the stuff I want included in the tar underneath, like: `etc/rc.d/init.d/glassfish3`, `opt/glassfish3/...`, and other directories and files under `opt/...`. When I do `tar zcvpf files.tgz *` it includes the intermediate directories (like `etc`, `etc/rc.d`, and `opt`) in the tar file. Then when I extract it into `/` on another system, it has the undesirable behavior of mucking with ownership and permissions on those directories. I really want to leave those alone and not touch them. So I thought I found a good way around this with:               find . -type f -print0 | tar zcvpf files.tgz --null --files-from -      which creates a tar that only includes files. This is great, it only gets the files I put in there... except I just discovered it's not picking up important leaf directories, like:               opt/glassfish3/glassfish/lib/asadmin      which is an empty directory (and needed by Glassfish3, or it will complain). **How can I create a tar file that skips intermediates but not final directories?** I have a feeling some find+awk magic might do it. It doesn't need to be a one-liner though, readability is important. Thanks. * * * **Edit** : I found this. Other/better ideas welcome:               cat <(find . -type f -print0) <(find . -type d -empty -print0) | tar zcvpf files.tgz --null --files-from -

title: `dd` to specific location

text: `dd` is a great tool for copying and conversion. Is there any way by `dd` (or by any other way), to dump the first few bytes from a file to an unmounted partition? Something like this: `dd if=hda2.pbr of=/dev/hda2 bs=512 count=1` The goal, I'm trying to achieve is to copy out the PBR of a partition to file and restore it as and when required. When that partition not required, then I will dump the PBR with some garbage value, so that underlying partition will fail to get mounted


title: Alt key not recognized - Dell Inspiron n4110/Mint 16 (Petra)

text: I'm running a fresh install of Mint 16 on an essentially-brand-new Dell Inspiron N4110. I booted to Kali Linux initially, and noticed `Alt``Tab`, `Alt``F4`, and `Alt``D` (address bar focus) weren't working in Iceweasel, which I dismissed as a minor glitch or a missing driver or something. After downloading & installing Mint, the `Alt` key still does not work. `xev` shows absolutely nothing during an `Alt` keypress (`LAlt` or `RAlt`). I've never had this problem before, and Google isn't turning up much. Has anyone else seen this, or have an idea of where to look? As far as I can tell, the rest of the keys are working fine, and the Fn key is in "normal" mode (`F12` = `F12`, as opposed to `F12` = `Mute`).

text: I had a RAID 0 on two EBS volumes running fine on EC2 until the instance was stopped, a snapshot of the EBS volumes created and then restarted again. Now when I go to mount the RAID array I can't seem to do so. `sudo mdadm --assemble -v /dev/md0 /dev/xvdj1 /dev/xvdk1` But when I try to mount `mount -t ext4 /dev/md0 /mnt` I get               mount: wrong fs type, bad option, bad superblock on /dev/md0,        missing codepage or helper program, or other error        In some cases useful info is found in syslog - try        dmesg | tail  or so      What am I doing wrong? EDIT: Yes, I'm sure the file system is ext4 and it has quite a bit of data on it.

title: Does a remote system accessed with SSH have a system clipboard?

text: According to wikipedia in the `bash` shell `control+u` > Clears the line content before the cursor and copies it into the clipboard If I'm ssh'ed into a box and try that, the text certainly disappears but I have no idea where it goes. Can I access it somehow? I don't want to have to use `xsel` or set up `x-forwarding`, I am just curious if it is stored in some register somewhere remotely. For example, I tried starting `vim` and typing `"*p` or `"+p` to paste from the system clibpoard but am not having any luck. If I use `control+u` remotely when ssh'ed to a box, where does it go, and can I access it?


title: End of lines problem in emacs when editing markdown texts via It's All Text

text: I want to edit markdown source in emacs using the It's All Text plugin for firefox. In markdown you have to add two spaces to the line-end to get a new line. Suppose there is such a newline in a markdown source. If I open this in emacs via It's All Text, change something else and save it then the two spaces at the end of the line dissapear which is very annoying. So is there a way to configure emacs not to touch such spaces at line ends in this case?


title: variable assignment from inside a bash script

text: This is obviously an SSCCE, so it makes (in itself) no sense. E.g. the variable assignment to `Y` is not used in this minimal example; I'm just trying to figure out the correct syntax to use for my actual case. I can do the following directly on the bash shell:               Y=10 echo foo      I can also have the following in a bash file `foo.sh`:               #!/bin/bash     X="echo foo"     $X      ... and then do a:               $./foo.sh     foo      However, when I have the following in a bash file:               #!/bin/bash     X="Y=10 echo foo"     $X      ... then, I get:               $ ./foo.sh      ./foo.sh: line 3: Y=10: command not found      What's the correct syntax to use for the above?

title: How are default permissions determined (on OS X)?

text: My (limited) understanding of basic Unix is that any files that are created will be created based on the permissions of the creating user. In particular, the group assigned will be the creating user's "default" group. But on OS X (10.8.2) I see different behavior. Even though my default group is my user account (my GID as listed by `id`), if I create a file in a directory with               drwx---r-x   MyName   MyName      or with               drwx------   MyName   MyName      it has               -rw-r--r--   MyName   MyName      while if I create a file in a director with               drwxr-xr-x   MyName   staff      it has               -rw-r--r--   MyName   staff       There are no extended attributes on any of the these directories, yet they behave as if something like `directory_inherit` and `file_inherit` are set, and as if read permission should always be given. Where are these default policies set in OS X (Mountain Lion)? How can they be configured? * * * I'm happy with the inheritance of group, but would ideally like files created in `-r` directories to be `-r` also; and would like "others" to never have any access. I suspect I can do something with `umask` to get this latter behavior, but I'd still like to be sure and to know where why the group is inherited from the containing directory.

What I'm not sure is how to tell it that I want it to paste that string at the end. I've tried using `&`, but that matches the `)`, not the `"\p*"`.

You actually _can_ get `^<foo>` to show up in the help, but only if you map `^<foo>`, which isn’t exactly what I want. ;)

It pulled in following packages -                 Installing     : agg-2.5-9.fc13.x86_64                                                                                1/6        Installing     : gtkglext-libs-1.2.0-10.fc12.x86_64                                                                                2/6        Installing     : boost-thread-1.44.0-7.fc14.x86_64                                                                                3/6        Installing     : boost-date-time-1.44.0-7.fc14.x86_64                                                                                4/6        Installing     : 1:gnash-0.8.8-4.fc14.x86_64                                                                                5/6        Installing     : 1:gnash-plugin-0.8.8-4.fc14.x86_64                                                                                6/6       Now, I tested the plugin and I didn't like it. I want to remove all these above packages which got installed with the plugin as I don't longer going to need them. How can I do this? I checked remove-with-plugin for yum but it pulls in all the packages which are currently depending on the packages. I understand the thought process behind showing what packages are getting affected - but I am wondering if there is any way of looking at the history with what package got installed when I installed a certain package. When gnash-plugin wasn't there firefox was running fine with but after I installation firefox is now depends on this new plugin. Has any one worked on differentiating hard-dependencies(hard means the program will break if that package is not there) and soft-dependencies ( soft means the program may not get affected fatally) ?


title: Securing VPS against access by server company

text: I have a few linux `VPS` boxes that contain the private keys to Bitcoin. I've taken a few steps to harden them:   * Blocked all ports except those needed for my server with uncomplicated firewall   * Disabled login with password; setup SSH keypairs; disabled root `ssh`   * clear `ssh` history after typing private key or password However, I noticed that within my hosting control panel I have the option to `Reset Root Password.` It seems that despite my hardening the server company has some kind of supervisor access that lets them reset the root password. How can they reset the root password? Is there a way to harden the server against internal access by the server company? Do I need to enable full disk encryption or home folder encryption?


title: Inkscape not opening after installed?

text: I just installed 14.04 on my laptop. The first thing I did was to install `inkscape` by using the instructions on this website. However, after installation, it does not appear if I search for it in the Unity dash. If I try running it from the command line, it says that it is not installed. But if I try to to install again, it says that the newest version is already installed. Additionally, Ubuntu Software Center says that it is installed. See the terminal output below. What should I do?                   mark@kitchencomputer:~$ inkscape         The program 'inkscape' is currently not installed. You can install it by typing:         sudo apt-get install inkscape         mark@kitchencomputer:~$ sudo apt-get install inkscape         Reading package lists...

title: LVM - failed to install bootloader

text: I have Mint 16 installed on an LVM system. I originally had 3 logical volumes: lvswap, lvrootone, and lvstorage, with Mint 16 installed on lvrootone. I was hoping to use this scheme to upgrade and try new distros by adding logical volumes, but hadn't done so until now, when I tried to install Mint17. While running under Mint 16 I created another logical volume, lvroottwo. I ran the Mint17 installer, choosing 'something else' and asked that Mint17's root file system be installed on lvroottwo. The installation proceeded but ended with (something like): 'failed to install bootloader'. I was given the option of trying to have bootloader installed onto sda, which I chose, but that failed too. I gave up, exited the installer and rebooted. It booted to the old Mint 16 as usual. I can mount lvroottwo and see the Mint17 installation there. What can I do to be able to boot to Mint17 or, preferably, to have a choice? What is the 'proper' way to use LVM in order to try new installations? As you can tell I haven't had any prior experience with the bootloader or anything concerning the boot process. Thanks for any help. * * * Pavel (his answer and comments are below) asks for details on how I tried to get it working. I didn't try anything. I don't know anything about boot or boot tools and did not know what to try. My question is: what should I try? Pavel also requested description of disk layout. Output from fdisk -l is below. (Please note that sdb is not being used. I added it to the volume group as a physical volume and tried to use it as a raid1 type mirror to one of the logical volumes on sda. But then the system would not boot. So using a live CD I removed the mirror and system booted again. I think that for this current question my experience with sdb could be ignored, but I need to learn about the boot process so I mention it here.) output from fdisk -l: > Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, > 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 > bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size > (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x000d8478 > > Device Boot Start End Blocks Id System /dev/sda1 * 2048 976773119 488385536 > 83 Linux > > Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, > 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 > bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size > (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 > > Disk /dev/mapper/vgpender-lvswap: 8589 MB, 8589934592 bytes 255 heads, 63 > sectors/track, 1044 cylinders, total 16777216 sectors Units = sectors of 1 * > 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O > size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 > > Disk /dev/mapper/vgpender-lvrootone: 26.8 GB, 26843545600 bytes 255 heads, > 63 sectors/track, 3263 cylinders, total 52428800 sectors Units = sectors of > 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: > 0x00000000 > > Disk /dev/mapper/vgpender-lvstorage: 375.8 GB, 375809638400 bytes 255 heads, > 63 sectors/track, 45689 cylinders, total 734003200 sectors Units = sectors > of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 > bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: > 0x00000000 > > Disk /dev/mapper/vgpender-lvroottwo: 26.8 GB, 26843545600 bytes 255 heads, > 63 sectors/track, 3263 cylinders, total 52428800 sectors Units = sectors of > 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes > I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: > 0x00000000


title: I can't get Cinnamon to stop freezing, how can I revert it back?

text: I have an issue, and I'm unsure if it is a bug or not but here's the skinny: I updated cinnamon from 1.6.7 to 1.8 (don't get me wrong, I love it BUT!) Ever since I did the update, Cinnamon has been freezing on me. The mouse moves, but nothing is click-able (so I can't right click the panel > Troubleshoot > restart cinnamon).   _\--My mindset for this is that the freezing can be tolerable if I can just restart cinnamon without having to continuously restart my computer about four to six times a day._ I can be in Firefox mid-type, mid-scroll, trying to minimize (one time, froze while trying to maximize), and trying to move the window. I opened up Skype, went to login and it froze. Opened up the Menu and it froze. Right clicked the desktop, tried to pick an option and it froze. I don't know if it is just me or not, but either way, there is a rather annoying issue on my hands. There were glitches in 1.6.7, but it never froze. _And I had the ability to right click the panel to restart Cinnamon to fix the issues then._ **Details:** Linux Mint 13 (cinnamon 1.8)   Processor: AMD Turion(tm) 64 X2 Mobile Technology TL-58 x 2   Graphics: Gallium 0.4 on NV4E   OS type: 32 bit **What I've Done So Far** went into tty2 and typed in               export DISPLAY=:0; cinnamon --replace &      The first response I received was               [1] 2940      followed up by               Window manager error: Unable to open X display      (Got the idea from Ubuntu SE and tried all the answers there too, nothing worked. The idea of just hitting 'r' and enter didn't help me restart cinnamon either.) The last thing I did was completely removed Cinnamon and then reinstalled it:               sudo apt-get --purge remove cinnamon       sudo apt-get install cinnamon      I restarted my computer, logged in, 5 minutes later, it froze. (:/ didn't help) Since I don't think I can fix this, is there a way to "roll-back" to 1.6.7.?

title: What is wrong with this "find all vim swap files and remove them with a confirmation" command?

text: I am trying to remove all vim swap file `*.swp` and remove them with a confirmation. The `find` command found the files, but `rm` says `No such file or directory` with the `-i` option. When I hardcode the path of the file and just use `rm -i` then it seems to work. See below               (doors)hobbes3@hobbes3 ~/Sites $ find mysite mysite_BAK -name *.swp -exec 'rm -i {}' \;     find: rm -i mysite/templates/.base.html.swp: No such file or directory     find: rm -i mysite/templates/doors/orders/.create.html.swp: No such file or directory     find: rm -i mysite/templates/doors/orders/.detail.html.swp: No such file or directory     find: rm -i mysite/templates/doors/orders/.list.html.swp: No such file or directory     (doors)hobbes3@hobbes3 ~/Sites $ rm -i mysite/templates/.base.html.swp      remove mysite/templates/.base.html.swp? n      I guess I'm doing something wrong with the `-exec` option. Any suggestions? Thanks in advance!


title: How do I set up alpine to read local Unix generated mail

text: Linux delivers mail to home directory: `/home/linker/Maildir` under which are 3 directories `new`, `cur`, `tmp`. When I type `mail` I get `mail: /home/linker/Maildir/: Is a directory`, which is not useful. I have installed alpine but can't get it access the Maildir directory (above) to read the mails in `new`. I guess its all about the `.pinerc`


title: List of script( location)s that get run automatically, and when?

text: Does anybody know (of a resource listing) what scripts are run automatically, and when, from the moment I startup the computer until it's shutdown again. I know several places where I can add scripts to run automatically, but I’ve never been able to figure out a more-or-less complete list. For example, I know these:   * `~/.profile` is executed on login   * I can use `crontab -e` to add scripts that will trigger on certain times and/or dates But I can't figure out where to put scripts so that they'll be executed   * after boot, before X is initialized   * after the X (or other graphical shell) is initialized, but before anyone's logged in   * after logging in on an X session   * before/after fast user switching   * before logging out of an X session   * before shutdown on the X shell   * after shutdown of X, before system halt   * after login/before logout via tty-1..6   * after login/before logout via SSH Is there such a list? If not, can we assemble one here?


title: Performing accurate snapshot and incremental backups to a remote server

text: I have a few Ubuntu (and potentially RHEL) servers I'd like to back up to a central backup server (via rsh/SSH). I'd like to do both snapshot and incremental backups. The goal is that if one of the backed-up servers were to suddenly die, I could install a bootstrap image, restore from the backup and ideally be up-and-running immediately thereafter. These servers have unique users and groups and some different gids and uids for the same names. I was considering rsync (local backups work fine, and I have fine-grained control so I can back up xattrs and ACLs as well) but then I realized rsync to a remote server likely won't retain these nuances as expected. So, what's a better way to accomplish this? Is there a package that is commonly used for this purpose?


title: Using external hard disk to boot 2 different computers with different hardware

text: I'm a CS student at my university, so I typically run a version of linux at my home computer when I do programming in C or other linux specific stuff. I really hate grub (it never seems to work for me), so I installed ubuntu on an external hard disk, and it boots and runs fine with only a few grub issues. My desktop has and AMD processor and an AMD graphics card. I want to take my laptop to school sometimes (I take my chromebook right now as its much lighter and easier to bike with) when I really need to crank out some work and would like to use ubuntu as well. I guess I am wondering what the best solution here would be: A) Is it possible to dual boot with these different graphics drivers/hardware? I built a vanilla linux kernel [an assignment for one of my classes] and it inserted its own drivers for each kernel version. Would it be possible to build another ubuntu kernel, make it in my grub file, and install only nvidia drivers, then boot that kernel when I use my laptop? (I don't even know if this is possible?) B) Just dual boot 2 ubuntu installations on the external disk? Would rather have one install if possible. Thanks, Mgamerz


title: GNU: Delayed jobs Queue

text: Is there a simple way for me to add a shell command to a list of jobs to have run on the system when I'm not logged in? For example: I SSH into my system, decide that I want to read an ebook later, but it's in the wrong format. I'll use Calibre to convert it, but this will take up the CPU for many minutes. I'm in no rush though, so I would like to tell my system to start the Calibre convert operation (just running a shell command) as soon as I log out of my SSH session. Then later when I SSH in again, my converted book will be waiting for me.

title: How to use wget or other tool to download a file, for which the link is hidden(activates on-click only)

text: I want to to download some subtitle files, stored in rar files form http://subs.sab.bz/ The site provides rss feeds for its new releases. Unfortunately, the link provided will open a download page, but will not get the file. The download page has a button in the middle, and clicking on it will trigger the download of the desired rar file. Anyway, if I right click and copy the link, and try to open it, the browser will open the download page itself, but will not download the file. When I try to use the download link of the file in wget and curl, a php file is downloaded. I read that in such cases a server- side script is used to pass the correct link to the client machine. So, I am looking for a way to force wget to emulate onclick action of this link. I know html css and javascript enough to find other properties of the download link. Can this even be done? PS. I am quite confused why this question was down-voted? Any good explanation, did I break any rules for posting or something, thank you..

text: My RHN Satellite (Spacewalk) server is having issues with monitoring. The Spacewalk Monitor Scout will not push out successfully. It always stops with a `Request Expired` status. I can't seem to find any error logs. I don't believe that it is a firewall or SELinux issue. I can run `/usr/bin/ssh -l nocpulse -p 4545 -i /var/lib/nocpulse/.ssh/nocpulse-identity -o StrictHostKeyChecking=no -o BatchMode=yes computername /bin/sh -s` And get results back from the client machine. But from the web console the scout expires. In addition, all of my monitor probes are stuck in an `Awaiting Update` status. The Spacewalk server public key is in the correct location on all clients `/var/lib/nocpulse/.ssh/authorized-keys`. I'm kind of at a loss. Any help is appreciated.


title: How to find which screen session is one working on

text: I use the screen program extensively. It has helped me tremendously by reducing the time spent in setting up session every day. However, now that I have >8 screens - I forget sometimes which screen I am in. Is there a way to find the name of the screen session that I am working in. screen -ls will list all the screen session. Is there a way to detach from all the currently active screen sessions - e.g. at the end of the day.

title: How can I low-level format flash memory in Linux?

text: My friend was having problems with a USB flash drive, and I suggested he do a low-level format. Then it occurred to me that I don't even know how to do that in Linux. So... how can I low-level format flash memory in Linux? My friend tried a "full format" on the drive in Windows and it failed.

title: Linux can't recognize the right password when ssh'ing?

I've tried it both as `root@localhost` and `chulhyun@localhost` (chulhyun is my user name).

title: Can't run vlock-cmatrixreloaded with acpid anymore, after switching to systemd

title: wi-fi working on and off, mostly off on a HP laptop

text: I have a HP laptop with Intel Centrino 2230 card. The system is Xubuntu 13. Wifi worked fine until it stopped a couple of days or maybe weeks ago. Now it's mostly off with some on episodes. Specifics: I can connect to a network and obtain an IP address, but can't ping the gateway. The network has WPA2. Setting wlan0 down and up doesn't help. Any idea on how to fix it? EDIT after the response: Windows WIFI on the same laptop works fine, so it's an issue with Linux configuration. I remember turning off N mode (don't remember how) because wi- fi was slow, that helped with speed.

title: How to recover data lost during aborted local drag and drop?

text: I have dragged and dropped a large amount of data between two tabs of Thunar (XFCE 4.10) but accidentally clicked cancel during the process. The data have been removed from the source folder and are of course incomplete on the destination folder. The source and the destination folder are on the same partition (ext4) of the same disk (so a bit different from File damaged/lost during transfer? Recovery possible?). I haven't touched anything since. The Thunar "free space" indicator still acts like the data are here. What can I try ? Why did it even move the data on the first place ?


title: Boot process hangs, can start with "single" + startx

text: Mint 16 Cinnamon x86_64 fully updated (kernel 3.11.0-14-generic). Drive is encrypted as well as user's home dir. I had been working for a few days with a new install of Mint 16 and have suspended/restarted without issues until today. Now the boot process hangs, but I can log in via "single" and X works with `startx`. The following are the symptoms that I have noticed:   * When the boot process is hung, if I try to log into an alternate tty the login appears to succeed but immediately exits back to a login prompt   * Last message in the hung boot process is:              Starting startpar bridge for notification of upstart job start/stop      , of which there are several.   * The last message in syslog from hung boot is:              dbus[1191]: [system] Successfully activated service 'org.freedesktop.ConsoleKit'        * Last line in kern.log is:              kernel: [   48.127483] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready        * Things that I recall doing directly before the breakage: installed wine, installed some i386 libs to run a prog in wine, installed clamav, installed `ttf-mscorefonts-installer`, installed `oracle-java7-installer` UPDATE: If I start single, and then run "service rcS start" I get the same effect as starting normal. In fact. I have moved all of the S* symlinks out of /etc/rcS.d/ and still experience the issue when starting the rcS service. If I manually start all of the services in rcS.d, I get no errors. I started them using "service ... start". I'm thinking now that this might be related to upstart?


title: Flash drive in OpenBSD: "specified device does not match mounted device"

text: I'm a relative BSD newb. I have a small server running OpenBSD 4.4. I'm trying to plug in a 16GB USB flash drive to move some files. I followed the guidance of the Disk Setup documentation, and found the label and filesystem of the desired partition. But when trying to mount the partition, I get the following:               # mount -t ext2fs /dev/sd1i /mnt/flash      mount_ext2fs: /dev/sd1i on /mnt/flash: specified device does not match mounted device      I googled a bit, but nothing I found was particularly helpful. Can anyone shed some light on this message? **Edit:** _Additional Info_               # disklabel sd1     disklabel: warning, DOS partition table with no valid OpenBSD partition     # /dev/rsd1c:     type: SCSI     disk: SCSI disk     label: SanDisk Ultra      flags:     bytes/sector: 512     sectors/track: 63     tracks/cylinder: 255     sectors/cylinder: 16065     cylinders: 1946     total sectors: 31266816     rpm: 3600     interleave: 1     trackskew: 0     cylinderskew: 0     headswitch: 0           # microseconds     track-to-track seek: 0  # microseconds     drivedata: 0           16 partitions:     #                size           offset  fstype [fsize bsize  cpg]       c:         31266816                0  unused      0     0             i:         31262427               63  ext2fs


title: Mouse clicks stop working after random time, using Awesome WM + Gnome

text: I'm using the Awesome Window Manager together with Gnome in Linux Mint. I experience the following problem several times a day: Suddenly the mouse partially stops working, which means that I'm still able to move the cursor, but any mouse clicks won't do anything. Moreover, the cursor doesn't change when it should, e.g. when hovering over links. This state doesn't change until restarting the computer or restarting the X server with Ctrl+Alt+Backspace. Despite this the system works quite normal. (I'm writing this message without mouse at the moment) I think it's very unlikely that it is the mouse as changing the mouse doesn't change the behaviour. To me, it feels a bit like some invisible window was put over the whole screen, or some application "captured" the mouse and didn't release it, but thats only speculation. I even tried it via TeamViewer, and it shows the same behaviour -- moving works, hovering and clicking does not. I should mention the problem is global, not limited to any special program. Now I know when the bug occurs exactly: If I click in a Gtk application (like Nautilus, Gedit, Ubuntu Software Center) somewhere in the menu bar or the toolbar where no menu or button is (e.g., right of the "Help" menu in Nautilus), then this bug occurs. If I close the corresponding application, it goes away. I'm going to start a new thread for this.


title: Simple bash script taking too long to execute

text: I wrote the following function in my `.bashrc` for use instead of `rm *` :               function re()     {     cp . -R /home/glset/ritwik/trash/     rm *     }      It works .. but it is very slow. Even for small files it takes too long to execute. It is always faster to just fire the two commands one after the other which defeats the purpose of the function in teh first place. Am I doing somethign wrong here ? What makes it take more time ?


title: Flag a package as being configured on Debian even if it's not

text: For various reasons, I have a package on my Debian system which cannot configure itself properly. I know why and I don't want to correct the problem right now. However, I want to avoid `apt` _trying_ to configure it each time I install an unrelated package (for at least 20 seconds). To do so, I would like to flag this package as being configured, even if it is not. That is, **make`apt` believe that it is configured**. How can I do that? _Some context:_ if you must know, my mysql database is corrupted. I will fix that later, but I did upgrade my mysql-server package in the meanwhile, and since that time, as the configuring script cannot succeed to launch the db- server, it fails, making `apt` painful to use.


title: What are some good profiling tools for Linux?

text: I'm looking for some good profiling tools for Linux like OProfile. What I would like to see is how the operating system manages the interrupts, cache, read/writes, etc (lots of other intricate operations inside the OS) for different applications and workloads. Ofcourse, I can select a bunch of different system monitoring tools like sar, iostat, vmstat and what not, but using different type of tools and synchronizing all the data is a pain, especially when you are monitoring cache line, interrupts, etc. Oprofile gives a nice overview and detailed analysis of what I want, but sometimes it fails to run on the latest kernels. I'm not sure why. But in any case, I would like to know if there is a nice alternative to this?


title: What are the advantages of Btrfs for end users?

text: Btrfs has begun to gain some momentum in replacing ext4 as the default filesystem of choice for a few distributions such as Fedora Core 16. It is experimentally available in a number of other distributions (From Wikipedia: openSUSE 11.3, SLES 11 SP1, Ubuntu 10.10, Sabayon Linux, RHEL6,MeeGo, Debian 6.0, and Slackware 13.37). I'm certainly not ready to convert all my workplace servers over (my file system choice is generally conservative), I'm considering using it at home and on select non-mission critical production machines at work. Btrfs brings a feature set that is similar to ZFS in many ways. I can understand why this would be desirable in an "enterprise" environment, especially with systems that focus on storage delivery. But how is this same feature set useful for end users? What advantages does Btrfs' feature list give me on machines whose primary function is not the presentation of storage? What advantages does it give me on my laptop? Outside of enterprise storage, why should I bother switching to Btrfs from the tried and true Ext filesystem?
