(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.

List directories recursively showing its sizes using only ls and grep
ls -lhR Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders. grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.

Uses lsof to display the full path of ".log" files opened by a specified PID.

Setting global redirection of STDERR to STDOUT in a script
You have a script where =ALL= STDERR should be redirected to STDIN and you don't want to add "2>&1" at the end of each command... E.G.: $ ls -al /foo/bar 2>&1 Than just add this piece of code at the beginning of your script! I hope this can help someone. :)

List just the executable files (or directories) in current directory
A bit shorter ;)

Display total Kb/Mb/Gb of a folder and each file

Edit a script that's somewhere in your path.
Often I need to edit a bash or perl script I've written. I know it's in my path but I don't feel like typing the whole path (or I don't remember the path).

Indent all the files in a project using emacs
use -iname \*[.ch] instead of -iname \*.c -o -iname \*.h
