Check These Out

Retrieve "last modified" timestamp of web resource in UTC seconds
This command line assumes that "${url}" is the URL of the web resource. It can be useful to check the "freshness" of a download URL before a GET request.

Use Linux coding style in C program
put "-linux" option into $HOME/.indent.pro to make it default

find an unused unprivileged TCP port
Not really better - just different ;) There's probably a really simple solution out there somewhere...

Find and copy scattered mp3 files into one directory
I used this command to recursively gather all mp3 files that were previously imported into their own directories (sorted by band name) in Songbird.

sqlite3 cmd to extract Firefox bookmarks from places.sqlite
Found this useful query at http://id.motd.org/pivot/entry.php?id=22. The b.parent=2 in the command refers to the bookmarks folder to extract. See the source webpage for additional info.

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.

check open ports without netstat or lsof

Burn an ISO on the command line.

find which lines in a file are longer than N characters
Filter out lines of input that contain 72, or fewer, characters. This uses bash only. ${#i} is the number of characters in variable i.

Command line progress bar
This command tar?s up a directory and sends the output to gzip, showing a rate of 223MB/s. This may require you installing the pv command. For debian based users out there: $ sudo aptitude install pv
