Count lines in a file with grep
Returns the number of lines in a file, emulates "wc -l" behavior with grep.

Show numerical values for each of the 256 colors in bash
I like the other three versions but one uses nested loops and another prints every color on a separate line. Both versions fail to reset colors before giving the prompt back. This version uses the column command to print a table so all the colors fit on one screen. It also resets colors back to normal before as a last step.

List all execs in $PATH, usefull for grepping the resulting list
##Dependancies: bash coreutils Many executables in $PATH have the keyword somewhere other than the beginning in their file names. The command is useful for exploring the executables in $PATH like this. $ find ${PATH//:/ } -executable -type f -printf "%f\n" |grep admin lpadmin time-admin network-admin svnadmin users-admin django-admin shares-admin services-admin

Install pip with Proxy

list block devices
Shows all block devices in a tree with descruptions of what they are.

pip install into current directory without virtualenv
For subsequent commands in the prefixed path: $ PYTHONPATH=$PWD/lib/python*/site-packages ./bin/pip --version

Transfer a file to multiple hosts over ssh
You can push files to up to 32 servers at once assuming ssh keys are in place. Great tool, it is part of the pssh suite.

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

Make all GUI stuff show up on the display connected to the computer (when you're logged in via SSH)
If you have multiple displays or monitors the DISPLAY environment variable will tell X where to send the output. This is very handy for setting up a mediacenter at home. You can plugin the computer to the TV and then ssh to the computer and set the DISPLAY as above, then run your program and it will show up on the TV.
