cmittendorf / pbcopy.rb
Created July 11, 2013 20:32
put this into your ~/.irbrc if you like do some text stuff in your ruby console which you want to paste somewhere else. Use "pbcopy a" to copy the contents of a to the pasteboard.
require 'tempfile'
def pbcopy(s)
tmp_file = Tempfile.new("pbcopy")
begin
tmp_file.write(s.to_s)
tmp_file.rewind
system "/bin/cat #{tmp_file.path} | /usr/bin/pbcopy"
ensure
tmp_file.close
