Play a random .avi file from a media tree

unsets variables used by the one-liner

sets up the IFS bash variable to not be affected by whitespace and disables extra glob expansion

uses read to slurp the results of the find command into an array

selects an element of the array at random to be passed as an argument to mplayer

Know a better way?

If you can do better, submit your command here.

What others think

If you don't care about embedded newlines in filenames, this version is a little easier on the eyes:

set -f; O=$IFS IFS=$'\n' files=($(find . -name '*.avi')) IFS=$O; set +f && echo "Running: mplayer \"${files[ $(( $RANDOM % ${#files[@]} )) ]}\""
