Check These Out

Plot frequency distribution of words from files on a terminal.
Uses the dumb terminal option in gnuplot to plot a graph of frequencies. In this case, we are looking at a frequency analysis of words in all of the .c files.

Check hashes of files installed by Debian packages, reporting only errors.

Find recursively, from current directory down, files and directories whose names contain single or multiple whitespaces and replace each such occurrence with a single underscore.
Note the g for global in the perl expression; without it, only the first occurrence in the name would be replaced.

list files recursively by size

Insert a comment on command line for reminder
Comments can be used directly on the command line so I can save in the history a brief description of what command does.

List processes sorted by CPU usage

Netcat & Tar
Create a tarball on the client and send it across the network with netcat on port 1234 where its extracted on the server in the current directory.

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.

Remove invalid key from the known_hosts file for the IP address of a host
Quick shortcut if you know the hostname and want to save yourself one step for looking up the IP address separately.

search google on os x
Searches Google, but requires no "", and will also search all terms input in the CL, eg: > google foo bar returns search URL "http://www.google.com/search?q=foo%20bar" You could also use awk to replace all spaces with a +, which is how the Google search handles spaces, but that makes it more than one line.
