Archive a directory with datestamp on filename
A useful bash function: gztardir() { if [ $# -ne 1 ] ; then echo "incorrect arguments: should be gztardir " else tar zcvf "${1%/}-$(date +%Y%m%d-%H%M).tar.gz" "$1" fi }

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Force the script to be started as root
Will run the script as root and exit if the wrong or no password is given. Also will keep the parameters active if any where given.

Expand shortened URLs
This relies on a public API from http://longurl.org. So, this has the weakness that if the service disappears, the function will break. However, it has the advantage that the shortened URL service will not be tracking your IP address and other metrics, but instead will track longurl.org. Thus, you can remain anonymous from the shortened URL services (although not anonymous from longurl.org). It does no sanity checking that you have provided an argument. If you do not provide one, "message" is displayed to STDOUT.

Install a basic FreeBSD system
Install a basic FreeBSD system on a distant server. I use this to install FreeBSD on servers that can only boot a Linux rescue system. This sytem loads on ram when booted, so it is possible to install freely. You can even install on ZFS root !

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.

Easily decode unix-time (funtion)
A shell function using perl to easily convert Unix-time to text. Put in in your ~/.bashrc or equivalent. Tested on Linux / Solaris Bourne, bash and zsh. using perl 5.6 and higher. (Does not require GNU date like some other commands)

Colorize matching string without skipping others
this is useful to highlight only some code without losing other lines (eg. software, logs, scripts)
