When I do a major change in my entities, I want to find a way to find all my Entities names and create the commande for me. So instead of doing ls src/Your/OwnBundle... and then do it manually, this helps a lot. Show Sample Output

shorter version. I believe find is faster than ls as well.

Provides a much cleaner, easier to read output than the closest alternative, ls -1R. This alternative makes it easier to differentiate directories from files: find . -printf '%y %p\n' | perl -ne 'if( m/(\w) (.*)\/(.*)/ ) { $t = $1; $p = $2; $f = $3; $t =~ s/[^d]/ /; $p =~ s/[^\/]/ /g; $p =~ s/\//|/g; print "$t $p/$f\n"; } elsif( m/(\w) (.*)/ ) { print "$1 $2\n"; } else { print "error interpreting: \"$_\"\n"; }' Show Sample Output

Find files matching multiple descriptions (*.c and *.cpp) excluding multiple directories (unit-test and android).

Using a for loop, rename all files with .MP3 extension to .mp3. Show Sample Output

Ever done a find to get content and been messed up by .git, .svn, .hg or the like spamming your results? Did you really want to grep over every copy of the file that existed in your git history? Replace: grep -r PATTERN . with: grep PATTERN -- $(have_here) or if you really have too many files to put in one argv: have_here | xargs grep PATTERN --

This will check if there are any empty directories, or newly emptied directories, in a list of directories. It will then delete all of those directories. It works with gnu find and OSX/BSD find.

Sometimes you want to see all of the systcls for a given $thing. I happened to need to easily look at all of the vm sysctls between two boxes and compare them. This is what I came up with. Show Sample Output

Watch out if you have several USB drives plugged in: it scans the whole /media/ folder !!! You can replace /media/ by the path of a specific USB drive (something like /media/F77A-530B/) I use a sound recorder and I want to plug the recorder and grab the most recent sound. That's what this command does. Use mv instead of cp to move instead of copy. Change *.wav to the required file type.

Handles spaces in file names and directories. Optionally change directories as well by pipe to tr from dirname.

rm /SOME/PATH/*, when you hit "argument list too long".

here's a version which works on OS X.
