Link a deep tree of files all into on directory
If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

Rename files in batch

convert all flac files in a folder to mp3 files with a bitrate of 192 kbps

Print a monthly calendar with today's date highlighted
The cal command is handy, but sometimes you want to quickly see today's date highlighted. That's why I came up with this quick command. Much like http://www.commandlinefu.com/commands/view/1342/show-this-months-calendar-with-todays-date-highlighted but cleaner and more succinct.

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.

Route outbound SMTP connections through a addtional IP address rather than your primary

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

disk space email alert
put it in crontab to get an alert when / is over 89% utilization.

add an mp3 audio track to a video

Replace spaces in filenames with underscores
I realize there's a few of these out there, but none exactly in this form, which seems the cleanest to me
