Check These Out

tcpdump whole packets to file in ascii and hex with ip adresses instead of hostname

Lists all listening ports together with the PID of the associated process
This command is more portable than it's cousin netstat. It works well on all the BSDs, GNU/Linux, AIX and Mac OS X. You won't find lsof by default on Solaris or HPUX by default, but packages exist around the web for installation, if needed, and the command works as shown. This is the most portable command I can find that lists listening ports and their associated pid.

Compare an archive with filesystem
and you quickly know the files you changed

Anti Syn Ddos
Ddos syn attack

Verify MD5SUMS but only print failures
All valid files are withheld so only failures show up. No output, all checks good.

Split lossless audio (ape, flac, wav, wv) by cue file
Do you have an entire album in a unique file and want to split it in individual tracks? If you also have the cue file you can do it! Packages for Debian-based systems users: * cuetools shntool * FLAC (.flac): flac * WavPack (.wv): wavpack * Monkey's Audio (.ape): libmac2 monkeys-audio (deb http://www.debian-multimedia.org sid main) NOTE: "sid" packages are unstable, but I didn't have problems with them. If you prefer, use the "stable" version repository. To transfer the tags, you can use this (works with .flac, .ogg and .mp3): $ cuetag sample.cue split-track*.flac

Top 10 Memory Processes
It displays the top 10 processes sorted by memory usage

show the real times iso of epochs for a given column
When you have one of those (log)files that only has epoch for time (since no one will ever look at them as a date) this is a way to get the human readable date/time and do further inspection. Mostly perl-fu :-/

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
