PATH manipulation in bash

Here are a couple of bash functions to add or remove an entry from the PATH environment variable. Add them to your ~/.bashrc.

To append an entry to PATH:

addpath ()  { export PATH="${PATH}:${1}"; }

To remove an entry from PATH:

rmpath ()   { export PATH=`ruby -e "puts ENV['PATH'].split(':').reject{|x|x==ARGV[0]}.join(':')" -- ${1}`; }
