On screen display of a command.
This is very useful if you need to show someone some text from a distance. (Like someone standing over your shoulder...) I'd recommend aliasing it to something like: alias osd_cat="osd_cat -o 400 -s 8 -c blue -d 60 -f -*-bitstream\ vera\ sans-*-*-*--200-*-*-*-*-*-*-*" xosd is the utility that provides osd_cat.

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Colorizes an access log
Puts a splash of color in your access logs. IP addresses are gray, 200 and 304 are green, all 4xx errors are red. Works well with e.g. "colorize access_log | less -R" if you want to see your colors while paging. Use as inspiration for other things you might be tailing, like syslog or vmstat Usage: $ tail -f access.log | colorize

Changes your group to the default group, has the same effect as sourcing your profile/rc file (in any shell) or logging out and back in again.
