I'm running a shell command like: plutil -convert xml1 "~/Library/Preferences/iCab/iCab 4 Bookmarks" Getting error: ~/Library/Preferences/iCab/iCab 4 Bookmarks: Permission denied How would I capture this error using a method of subprocess? I read the doc at http://docs.python.org/release/3.0.1/library/subprocess.html but confess I don't understand it. -- Gnarlie http://Gnarlodious.com/
