ok, it seems that the error is normal, and it should work. Are you sure it does not just work :-) You could check if the attached program outputs: $ ./catchio /does/not/exist: executeFile: does not exist (No such file or directory) Error caught Thanks, Joachim -- Joachim "nomeata" Breitner Debian Developer [email protected] | ICQ# 74513189 | GPG-Keyid: 4743206C JID: [email protected] | http://people.debian.org/~nomeata
