Check These Out

Speed up launch of liferea
If you use liferea frequently, you will see obvious speedup after you executed this command.

Shows what processes need to be restarted after system upgrade
emerge,apt-get,yum... all update your system. This will at some point replace either a runtime dependency or a process (which is still running). This oneliner will list what processes need to be restarted

see the TIME_WAIT and ESTABLISHED nums of the network

draw line separator (using knoppix5 idea)

Picture Renamer

List the size (in human readable form) of all sub folders from the current location
Tested on MacOS and GNU/Linux. It works in dirs containing files starting with '-'. It runs 'du' only once. It sorts according to size. It treats 1K=1000 (and not 1024)

Discovering all open files/dirs underneath a directory
It may be helpful in case you need to umount a directory and some process is preventing you to do so keeping the folder busy. The lsof may process the +D option slowly and may require a significant amount of memory because it will descend the full dir tree. On the other hand it will neither follow symlinks nor other file systems.

Ping sweep without NMAP
Waits for all pings to complete and returns ip with mac address

Multiple variable assignments from command output in BASH
It's quite easy to capture the output of a command and assign it in a shell's variable: $ day=$(date +%d) $ month=$(date +%m) But, what if we want to perform the same task with just one program invocation? Here comes the power of eval! date(1) outputs a string like "day=29; month=07; year=11" (notice the semicolons I added on purpose at date's custom output) which is a legal shell line. This like is then parsed and executed by the shell once again with the help of eval. Just setting 3 variables! Inspired by LinuxJournal's column "Dave Taylor's Work the Shell".
