Infinite loop ssh

cleanup /tmp directory
Cleans all files in /tmp that have been accessed at least 2 days ago.

Resets your MAC to a random MAC address to make you harder to find.
Next time you are leaching off of someone else's wifi use this command before you start your bittorrent ...for legitimate files only of course. It creates a hexidecimal string using md5sum from the first few lines of /dev/urandom and splices it into the proper MAC address format. Then it changes your MAC and resets your wireless (wlan0:0).

Lists installed kernels

Find the package that installed a command

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Enable programmable bash completion in debian lenny
The really awesome bash completion in debian seems to be an extra package now, which has to be installed. After sourcing /etc/bash_completion it completes almost everything (package names in apt... etc) :-) To make this permanent, put something like this in your .bashrc: if [ -f /etc/bash_completion]; then source /etc/bash_completion fi

Go up multiple levels of directories quickly and easily.

Convert JSON to YAML (unicode safe)
If you tried the other Python version of Convert JSON to YAML and you end up with lines that has "!!python/unicode", this version of the command is for you.

Apply permissions only to files
To apply only to dirs: $ chmod 755 $(find . -type d) Use -R parameters for recursive walk.
