Check These Out

Find all files currently open in Vim and/or gVim
Catches .swp, .swo, .swn, etc. If you have access to lsof, it'll give you more compressed output and show you the associated terminals (e.g., pts/5, which you could then use 'w' to figure out where it's originating from): lsof | grep '\.sw.$' If you have swp files turned off, you can do something like: ps x | grep '[g,v]im', but it won't tell you about files open in buffers, via :e [file].

Get the total length of time in hours:minutes:seconds (HH:MM:SS) of all video (or audio) in the current dir (and below)
change the *.avi to whatever you want to match, you can remove it altogether if you want to check all files.

Search for in which package the specified file is included.

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Delete a file/directory walking subdirectories (bash4 or zsh)

find directory with most inodes/files
Find which directory in one filesystem that contains most inodes or files.

Display a random crass ascii art from www.asciiartfarts.com
Optionally, pipe the output into http://sed.sourceforge.net/grabbag/scripts/html2iso.sed Or: wget -qO - http://www.asciiartfarts.com/random.cgi | sed -n '//,//p' | sed -n '/

Belgian banking "structured communication"
Derived from current time down to minutes.

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Show a config file without comments
