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.
<geshi lang="ruby">
#!/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(':')}\""
</geshi>
