  • WSL: Change the current directory converting a Windows path to a Linux Path

    The Windows Subsystem for Linux (WSL) is a compatibility layer for running binary Linux executables natively in Windows. A folder such as "C:\Program Files (x86)\Common Files" is represented as "/mnt/c/Program Files (x86)/Common Files". This function allows you to change the current directory to a Windows folder.

  • wget, tar xzvf, cd, ls

    Combines a few repetitive tasks when compiling source code. Especially useful when a hypen in a file-name breaks tab completion. 1.) wget source.tar.gz 2.) tar xzvf source.tar.gz 3.) cd source 4.) ls From there you can run ./configure, make and etc. Show Sample Output

  • free some harddrive space by garbage collecting in all your git repos

    Assumes you've cd'd to the folder in which all your git repos reside; you could run it from ~ without -maxdepth, although that might make find take quite a while longer. If you have several processor cores, but not that much ram, you might want to run git config --global pack.threads 1 first, since gc-ing can eat lots of ram. Show Sample Output


    -1
    find . -maxdepth 2 -type d -name '.git' -print0 | while read -d ''; do (cd "$REPLY"; git gc); done

  • Stores current working directory before exit and restores it on a new bash start

    this command will add the following two lines into the ~/.bash_aliases: alias exit='pwd > ~/.lastdir;exit' [ -n "$(cat .lastdir 2>/dev/null)" ] && cd "$(cat .lastdir)" or redirect it to the ~/.bashrc if you like Donno, I find it usefull. You may also define an alias for 'cd ~' like - alias cdh='cd ~'


    -1
    echo -e 'alias exit='\''pwd > ~/.lastdir;exit'\''\n[ -n "$(cat .lastdir 2>/dev/null)" ] && cd "$(cat .lastdir)"' >> ~/.bash_aliases

  • Directly change directory without having to specify drive letter change command

    In the Windows cmd.exe window, you can change the directory using cd, but if you need to go to a directory on another drive, you need to type in the drive letter and colon first (e.g. d:). With the /d on cd, you don't need this intermediate step. cd /? Tested on Windows XP Show Sample Output


    -2
    cd /d d:\Windows

  • Quick alias for playing music.

    An alias i made for myself to play music in a faster way. Works great when you have Guake / Tilda installed (Console that drops down like in the game QUAKE) --- I put this in my bash_alias file (I'm on ubuntu, the bash_alias file does autostart with the right config) but it works putting it in bashrc too. Or anything that autostarts when the console is opened. --- Needs Mplayer and music files to work. With out music theres nothing to play! Oh, and also, without modification, this alias will try to play stuff from your ~/Music folder! (case sensitive). Make sure that folder exists and has music OR edit this alias to fit your needs. Show Sample Output


    -2
    alias mux='clear && cd ~/Music/ && ls && echo -n "File> " && read msi && mplayer ~/Music/$msi'

  • Bulk copy large blocks of data between File Systems (run as root iff you do not own all of the files!)

    Using tape archive create a tar file in Stdout (-) and pipe that into a compound command to extract the tar file from Stdin at the destination. This similar to "Copy via tar pipe ...", but copies across file systems boundaries. I prefer to use cp -pr for copying within the same file system. Show Sample Output


    -2
    tar cpof - src |( cd des; tar xpof -)

  • Update many subversion projects which reside in one directory

    If you have a directory with many working copies of various subversion projects and you want to update them all at once, this one may be for you. Show Sample Output

  • sshdo, an alternative to sudo

    Run program as root by SSH key forwarding instead of sudoers. Put this alias line in .bashrc or wherever you like. Alias arguments might need extra escaping. You might wonder about security. But you'd block out root login as much as possible of course. In sshd_config you put this: PermitRootLogin no Match Address 127.0.0.1   PermitRootLogin without-password


    -2
    alias sshdo='ssh -q -t root@localhost -- cd $PWD \&\& sudo'

  • Find out the starting directory of a script

    I think this is the cleanest way of getting the current working directory of a script. It also works on osx, Linux, and probably bsd as well..

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

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Schedule Nice Background Commands That Won't Die on Logout - Alternative to nohup and at
Check out the usage of 'trap', you may not have seen this one much. This command provides a way to schedule commands at certain times by running them after sleep finishes sleeping. In the example 'sleep 2h' sleeps for 2 hours. What is cool about this command is that it uses the 'trap' builtin bash command to remove the SIGHUP trap that normally exits all processes started by the shell upon logout. The 'trap 1' command then restores the normal SIGHUP behaviour. It also uses the 'nice -n 19' command which causes the sleep process to be run with minimal CPU. Further, it runs all the commands within the 2nd parentheses in the background. This is sweet cuz you can fire off as many of these as you want. Very helpful for shell scripts.

Open Remote Desktop (RDP) from command line having a custom screen size
This example uses xfreerdp, which builds upon the development of rdesktop. This example usage will also send you the remote machine's sound.

Repeat a command until stopped
In this case it runs the command 'curl localhost:3000/site/sha' waiting the amount of time in sleep, ie: 1 second between runs, appending each run to the console. This works well for any command where the output is less than your line width This is unlike watch, because watch always clears the display.

faster version of ls *
I know its not much but is very useful in time consuming scripts (cron, rc.d, etc).

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

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Record a screencast and convert it to an mpeg
Grab X11 input and create an MPEG at 25 fps with the resolution 800x600

Lists unambigously names of all xml elements used in files in current directory
This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.

Recurse through directories easily
This is a simple case of recursing through all directories, adding the '.bak' extension to every file. Of course, the 'cp $file $file.bak' could be any code you need to apply to your recursion, including tests, other functions, creating variables, doing math, etc. Simple and clean recursion.

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.
