Matrix Style
It's the same command as submitted, but first with a command to make all characters green. It's the only way it looked "matrix-like" on my gnome-terminal.

Test python regular expressions
One can test their python regex matching using this shell function. for e.g. $ rgx_match "translate\s*\(([0-9-.]+),([0-9-.]+)\)" "translate(162.11517,76.817357)" ('162.11517', '76.817357')

Command line progress bar
This command tar?s up a directory and sends the output to gzip, showing a rate of 223MB/s. This may require you installing the pv command. For debian based users out there: $ sudo aptitude install pv

Sort files in folders alphabetically
Creates one letter folders in the current directory and moves files with corresponding initial in the folder.

list files recursively by size

archive all files containing local changes (svn)
This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

check open ports without netstat or lsof

Simplest port scanner
Very handy way to perform a host scan if you don't have nmap,ncat,nc ...or other tools installed locally. When executing a command on a /dev/tcp/$host/$port pseudo-device file, Bash opens a TCP connection to the associated socket and UDP connection when using /dev/udp/$host/$port.A simlpe way to get servers banner is to run this command "cat < /dev/tcp/localhost/25" , here you will get mail server's banner. NOTE: Bash, as packaged for Debian, does not support using the /dev/tcp and /dev/udp pseudo-device it's not enabled by default Because bash in Debian is compiled with ?disable-net-redirections.

Print a list of installed Perl modules
This version works on an AIX system on which I have very limited permissions. The other version fails with "Can't open file /usr/opt/perl588/lib/site_perl/5.8.8/aix/auto/DBI/.packlist".

Show bandwidth use oneliner
poorman's ifstat using just sh and awk. You must change "eth0" with your interface's name.
