  • 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. Show Sample Output

  • Generate CHECK TABLE statements for all MySQL database tables on a server

    This command will generate "CHECK TABLE `db_name.table_name` ;" statements for all tables present in databases on a MySQL server, which can be piped into the mysql command.

  • 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..

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.

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id
If you use Mac OS X or some other *nix variant that doesn't come with ssh-copy-id, this one-liner will allow you to add your public key to a remote machine so you can subsequently ssh to that machine without a password.

Rename all .jpeg and .JPG files to have .jpg extension
the "i" controls case sensitiveness. It's slightly inefficient since it uselessly renames .jpg to .jpg, but that's more than compensated by launching only one process instead of two, besides being shorter to write.

PRINT LINE the width of screen or specified using any char including Colors, Escapes and metachars
One of the first functions programmers learn is how to print a line. This is my 100% bash builtin function to do it, which makes it as optimal as a function can be. The COLUMNS environment variable is also set by bash (including bash resetting its value when you resize your term) so its very efficient. I like pretty-output in my shells and have experimented with several ways to output a line the width of the screen using a minimal amount of code. This is like version 9,000 lol. This function is what I use, though when using colors or other terminal features I create separate functions that call this one, since this is the lowest level type of function. It might be better named printl(), but since I use it so much it's more optimal to have the name contain less chars (both for my programming and for the internal workings). If you do use terminal escapes this will reset to default. $ tput sgr0 For implementation ideas, check my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

Rename files in batch

Display 16 largest installed RPMs in size order, largest first
Interesting to see which packages are larger than the kernel package. Useful to understand which RPMs might be candidates to remove if drive space is restricted.

Purge configuration files of removed packages on debian based systems
also search with aptitude search '~c'

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"

lists files and folders in a folder
lists files and folders in a folder with summary.

Smiley Face Bash Prompt
If your last command was a dud, your bash prompt will be angry at you. Otherwise it's happy. Soon you will crave its constant approval and your linux skills will improve simply to avoid low self-esteem.
