Unzip multi-part zip archive

"What the hell is running on?!" Easily snoop your system's RAM consumption
Works on most unixes, on OpenBSD replace the "-g" parameter at the sort with a "-n".

zsh suffix to inform you about long command ending
make, find and a lot of other programs can take a lot of time. And can do not. Supppose you write a long, complicated command and wonder if it will be done in 3 seconds or 20 minutes. Just add "R" (without quotes) suffix to it and you can do other things: zsh will inform you when you can see the results. You can replace zenity with other X Window dialogs program.

Tar files matching a certain wildcard
This is a shortcut to tar up all files matching a wildcard. Tar doesn't have the --include (apparently).

Selecting a random file/folder of a folder
Also looks in subfolders

Random line from bash.org (funny IRC quotes)
bash.org is a collection of funny quotes from IRC. WARNING: some of the quotes contain "adult" jokes... may be embarrassing if your boss sees them... Thanks to Chen for the idea and initial version! This script downloads a page with random quotes, filters the html to retrieve just one liners quotes and outputs the first one. Just barely under the required 255 chars :) Improvment: You can replace the head -1 at the end by: $awk 'length($0)>0 {printf( $0 "\n%%\n" )}' > bash_quotes.txt which will separate the quotes with a "%" and place it in the file. and then: $strfile bash_quotes.txt which will make the file ready for the fortune command and then you can: $fortune bash_quotes.txt which will give you a random quote from those in the downloaded file. I download a file periodically and then use the fortune in .bashrc so I see a funny quote every time I open a terminal.
