Sum file sizes
Even simpler! Use du ... the -s and -c flags summarize and print a grand total of all files recursively. The -b flag prints in byte format. You can use the -h flag instead to print in human readable format.

list files recursively by size

Recursively grep for string and format output for vi(m)
This is a big time saver for me. I often grep source code and need to edit the findings. A single highlight of the mouse and middle mouse click (in gnome terminal) and I'm editing the exact line I just found. The color highlighting helps interpret the data.

find text in a file
this will find text in the directory you specify and give you line where it appears.

Get all URLs from webpage via Regular Expression
Get all URLs from website via Regular Expression... You must have lynx installed in your computer to execute the command. --> lynx --dump "" | egrep -o "" - Must substitute it for the website path that you want to extract the URLs - Regular Expression that you wanna filter the website

dstat - a mix of vmstat, iostat, netstat, ps, sar...
This is a very powerful command line tool to gather statistics for a Linux system. http://dag.wieers.com/home-made/dstat/

climagic's New Year's Countdown clock
This is the 140 character long new year's countdown timer that was posted to the climagic account on twitter and identi.ca. There are saner ways of doing this of course, but probably none of those would fit. Uses the figlet command, but of course you can replace figlet with just echo if you want.

Ext3 format Terabytes in Seconds

Find default gateway

Using numsum to sum a column of numbers.
if you, like me, do not have the numsum, this way can do the same.
