Send a backup job to a remote tape drive on another machine over SSH
I use this all the time for taking manual backups of stuff i want to keep but not important enough to backup regularly.

Combining text files into one file

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Displays the attempted user name, ip address, and time of SSH failed logins on Debian machines
A variation of a script I found on this site and then slimmed down to just use awk. It displays all users who have attempted to login to the box and failed using SSH. Pipe it to the sort command to see which usernames have the most failed logins.

grep -v with multiple patterns.
You can use -e to pass multiple patterns.

Update twitter via curl (and also set the "from" bit)
An improvement of the original (at: http://www.commandlinefu.com/commands/view/2872/update-twitter-via-curl) in the sense that you see a "from cURL" under your status message instead of just a "from API" ;-) Twitter automatically links it to the cURL home page.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Find all symlinks that link to directories

bulk rename files with sed, one-liner
Far from my favorite, but works in sh and with an old sed that doesn't support '-E'

rsync + find
use find with rsync
