cleanpath

Simple tool to clean up PATH like strings by removing redundant and incorrect entries but keeping the relative order of the paths that remain.

For example:

$ export FAKEPATH=/usr/bin:/usr/local/bin:/usr/bin:/usr/sbin:.
$ export FAKEPATH=$(cleanpath $FAKEPATH)
$ echo $FAKEPATH
/usr/bin:/usr/local/bin:/usr/sbin

Notice:

1. Redundant paths removed, but relative order of first occurence is maintained.
2. Relative (unsafe) paths removed.
