Display the top ten running processes - sorted by memory usage

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Add a shadow to picture
Please take notice that if you are going to use an JPG file for shadow effect, let change -background none to -background white! Because -background none make a transparent effect while JPG doesn't support transparent! And when viewing, you will get a bacl box! So we will use an white background under! We can use other color as well!

Test http request every second, fancy display.
Use the command watch, which is really hard to pass nested quotes to, and insert newlines where they are supposed to go in the HTTP request. that is after 1.1 after the host and two newlines at the end before the EOF. i use this all day what? no support for HEREDOCs on commandlinefu's interface? need more fu.
