Often I need to remove something off my path. For example, when building certain tools, I don't want Sun's cc compiler present.

Here's a simple ruby script I use to find the program, and display what my path needs to be changed to.

#!/bin/env ruby
 
# a simple script to help clean up one's path.
 
path = ENV['PATH'].split(':').uniq
 
args = ARGV.clone
while args.size > 0 do
    cmd = args.shift
    type = ''
    while !type.match(/not found/)
      type = `type #{cmd} 2>&1`.chomp
      if type =~ /(#{cmd}) is (.*)/ then
        dir = File.dirname($2).to_s
        puts "removing #{dir}"
        if !path.delete(dir) then
          puts "failed to find #{dir} on #{path.join(':')}"
          exit 1
        end
        ENV['PATH'] = path.join(':')
      end
    end
end
 
puts "export PATH=\"#{path.join(':')}\""
