Extract audio from a video
With the -vn switch we make our intentions clear and ask FFmpeg not to bother itself with the video. Next we specify the audio codec copy, which tells FFmpeg to use the same codec to encode the audio, which it uses to decode it. To keep things simple, we'll just keep the sampling and bitrate values the same.

See OpenVZ Container id's of top 10 running processes by %cpu
This command will list the PID, VEID, and Name of the 10 highest cpu using processes on a openvz host. You must have vzpid installed.

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

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)

Convert all .wav to .mp3
Audio convert is a script that uses zenity and lame to transcode virtually any format to any other format provided you have the libraries installed to do so.

Shows cpu load in percent
Show the current load of the CPU as a percentage. Read the load from /proc/loadavg and convert it using sed: Strip everything after the first whitespace: $ sed -e 's/ .*//' Delete the decimal point: $ sed -e 's/\.//' Remove leading zeroes: $ sed -e 's/^0*//'

print a python-script (or any other code) with syntax-highlighting and no loss of indentation

Greets the user appropriately

Create thumbnails and a HTML page for listing them (with links to sources)
The input images are assume to have the "JPG" extension. Mogrify will overwrite any gif images with the same name! Will not work with names with spaces.

Execute a command at a given time
This is an alternative to cron which allows a one-off task to be scheduled for a certain time.
