Send pop-up notifications on Gnome

The title is optional. Options: -t: expire time in milliseconds. -u: urgency (low, normal, critical). -i: icon path. On Debian-based systems you may need to install the 'libnotify-bin' package. Useful to advise when a wget download or a simulation ends. Example: wget URL ; notify-send "Done"

(Debian/Ubuntu) Discover what package a file belongs to

'dpkg -S' just matches the string you supply it, so just using 'ls' as an argument matches any file from any package that has 'ls' anywhere in the filename. So usually it's a good idea to use an absolute path. You can see in the second example that 12 thousand files that are known to dpkg match the bare string 'ls'. Show Sample Output

```
user@host:$ dpkg -S /bin/ls
coreutils: /bin/ls
user@host:$ dpkg -S ls | wc -l

Tell local Debian machine to install packages used by remote Debian machine

(also works on Ubuntu) Copies the 'install,' 'hold,' 'deinstall' and 'purge' states of packages on the remote machine to be matched on the local machine. Note: if packages were installed on the local machine that were never installed on the remote machine, they will not be deinstalled by this operation.

Limit bandwidth usage by apt-get

Limits the usage of bandwidth by apt-get, in the example the command will use 30Kb/s ;) It should work for most apt-get actions (install, update, upgrade, dist-upgrade, etc.)

Find running binary executables that were not installed using dpkg

This helped me find a botnet that had made into my system. Of course, this is not a foolproof or guarantied way to find all of them or even most of them. But it helped me find it.

put an unpacked .deb package back together

If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modi‐fied), the new package will inherit the changes. This way you can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere. Note: dpkg-repack will place the created package in the current directory. Show Sample Output

(Debian/Ubuntu) Discover what package a file belongs to

Works similar to dpkg -S, but uses the locatedb and is thus inarguably a lot faster - if the locatedb is current.

Remove all unused kernels with apt-get

Note the double space: "...^ii␣␣linux-image-2..." Like 5813, but fixes two bugs: [1]This leaves the meta-packages 'linux-headers-generic' and 'linux-image-generic' alone so that automatic upgrades work correctly in the future. [2]Kernels newer than the currently running one are left alone (this can happen if you didn't reboot after installing a new kernel). I'm bummed that this took 228 characters. I'd like to see a simpler version. Show Sample Output

Calculates the size on disk for each package installed on the filesystem (or removed but not purged). This is missing the | sort -rn which would put the biggest packges on top. That was purposely left out as the command is slightly on the slow side Also you may need to run this as root as some files can only be checked by du if you can read them ;) Show Sample Output

Search for packages, ranked by popularity

This will take the packages matching a given `apt-cache search` query (a collection of AND'd words or regexps) and tell you how popular they are. This is particularly nice for those times you have to figure out which solution to use for e.g. a PDF reader or a VNC client. Substitute "ubuntu.com" for "debian.org" if you want this to use Ubuntu's data instead. Everything else will work perfectly. Show Sample Output

apt-popcon() { (echo \#rank; apt-cache search "$@" |awk '$1 !~ /^lib/ {print " "$1" "}') |grep -Ff- <(wget -qqO- http://popcon.debian.org/by_inst.gz |gunzip); }

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands

Check These Out

Find the ratio between ram usage and swap usage.

it provides the ratio used for the RAM and The SWAP under Linux. When swappiness is high, Swap usage is high. When swappiness is low, Ram usage is high.

search installed files of package, that doesn't remember his name well. On rpm systems

rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful. change PACKAGENAME to any package do you want to search

list block devices

Shows all block devices in a tree with descruptions of what they are.

Display text as though it is being typed out in real time

Pipe Viewer allows you to monitor the progress of a data transfer or command, or to show the time elapsed, among other things. In this use, it limits the transfer rate of the echo command to 10 bytes per second, making your text appear to be typed out in real time as in Hollywood movies. Fun!

vim's pastetoggle: when you press f9 'paste' is on , press f9 again and 'paste' is off, and so forth (works in insert-mode and command-mode)

list unique file extensions recursively for a path, include extension frequency stats

Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')

Remove today's Debian installed packages

Copy file to a Windows/Samba share without mounting it

This commando copies the file (which must reside in the current directory) to //<server>/<share-name>/<subdirectory>/<file> through the CIFS protocol (Samba share or Windows Share). It doesn't require you to mount the filesystem first. --directory "<subdirectory>" may be omitted in order to copy the file the the root of the share. The "%password" part may also be omitted. If doing so, smbclient will ask for the password interactively. To copy a file from a Windows/Samba share, change "put" for "get". $ smbclient --user=user%password --directory "<subdirectory>" --command "get <file>" //<server>/<share-name>

Blacklist usb storage

Some times you may ban usb to protect thefting of your personal data. Blacklist the usb_storage module by adding blacklist usb_storage to /etc/modprobe.d/blacklist.conf. To load the module manually, $sudo modprobe usb_storage.

Print permanent subtitles on a video (international edition :) )

If it's Hebrew [most probably all RTL languages. Comments?], add -flip-hebrew and -noflip-hebrew-commas to the mplayer switches: $ transcode -i myvideo.avi -x mplayer="-utf8 -flip-hebrew -noflip-hebrew-commas -sub myvideo.srt" -o myvideo_subtitled.avi -y xvid

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
