And if you only need simple messages, then there's nothing wrong with having to quote the "on success" command: $ when -t -c "xmessage Success" <command> <args...> The advantage of specifying the message command as an argument (as opposed to &&) is that it allows you to pass through the return value of the main command. For example, if your long-running program is still running after the timeout, you get the message; but it may fail later, and you want to know about that too. $ when -t -c 'logger "Service started successfully"' non-forking-service || logger "Service exited unexpectedly" ----- Samuel Holland <sam...@sholland.net>
