Convert seconds to human-readable format
This example, for example, produces the output, "Fri Feb 13 15:26:30 EST 2009"

Remove all HTML tags from a file

Quickly re-execute a recent command in bash
! will expand to the last time you ran , options and all. It's a nicer alternative to ^R for simple cases, and it's quite helpful for those long commands you run every now and then and haven't made aliases or functions for. It's similar to command 3966, in some sense.

Top ten (or whatever) memory utilizing processes (with children aggregate) - Can be done without the multi-dimensional array

Check reverse DNS
I'm just a simple programmer. I find dig too verbose. host tells me alias(es) and IP address in a quick to grok format with nothing special to remember for input parameters. With thanks to http://www.cyberciti.biz/faq/how-to-test-or-check-reverse-dns/

Function to change prompt
Bash function to change your default prompt to something simpler and restore it to normal afterwards.

RTFM function
Same as the other rtfm's, but using the more correct xdg-open instead of $BROWSER. I can't find a way to open info only if the term exists, so it stays out of my version.

calculate in commandline with bash
Only works for integer arithmetic.

Find the package that installed a command

Create a pdf version of a manpage
Quick and dirty version. I made a version that checks if a manpage exists (but it's not a oneliner). You must have ps2pdf and of course Ghostscript installed in your box. Enhancements appreciated :-)
