Written for Mac OSX. When you are working in a project and want to open it on Github.com, just type "gh" and your default browser will open with the repo you are in. Works for submodules, and repo's that you don't own. You'll need to copy / paste this command into a gh.sh file, then create an alias in your bash or zsh profile to the gh.sh script. Detailed instructions here if you still need help: http://gist.github.com/1917716

This revision to my command (command #8851) was called for when it failed to find the parent package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh. This revision fixes this newfound issue, while ensuring fixes of other older issues work too. Show Sample Output
6function whichpkg() { readlink -f "$(which $1)" | xargs --no-run-if-empty dpkg -S; } -
Sometimes you unzip a file that has no root folder and it spews files all over the place. This will clean up all of those files by deleting them. Show Sample Output
0unzip -l filename.zip |awk '{ if($4 != "Name" && $4 != "----") print $4}'|xargs -t rm -rf {} -
You could avoid xargs and sed in this case (shorter command and less forking): At least bash and zsh have some mighty string modifiers. I would also suggest using find with exec option to get more flexibility. You may leave out or include "special" file for example.
0for i in /usr/bin/* ;do touch ${i##*/}; done -
Helps if you accidentally deleted files from an svn repo with plain rm and you would like to mark them for svn to delete too.
0svn status|grep -iR '^!'|sed 's/!/ /g'|xargs -i svn rm '{}' -
Tells you everything you could ever want to know about all files and subdirectories. Great for package creators. Totally secure too. On my Slackware box, this gets set upon login:
LS_OPTIONS='-F -b -T 0 --color=auto'andalias ls='/bin/ls $LS_OPTIONS'which works great. Show Sample Output2lsr() { find "${@:-.}" -print0 |sort -z |xargs -0 ls $LS_OPTIONS -dla; } -
Grabs the Apache config file (yielded from httpd) and returns the path specified as DocumentRoot. Show Sample Output

For instance:
find . -type f -name '*.wav' -print0 |xargs -0 -P 3 -n 1 flac -V8will encode all .wav files into FLAC in parallel. Explanation of xargs flags: -P [max-procs]: Max number of invocations to run at once. Set to 0 to run all at once [potentially dangerous re: excessive RAM usage]. -n [max-args]: Max number of arguments from the list to send to each invocation. -0: Stdin is a null-terminated list. I use xargs to build parallel-processing frameworks into my scripts like the one here: http://pastebin.com/1GvcifYa2xargs -P 3 -n 1 <COMMAND> < <FILE_LIST> -
