in thread system() requires double ctrl-c

For people that do error checking, it's not a problem. die if !system("some_long_running_shell_command");

You mean die if system(...) as system returns 0 on success ... ok, this works for simple scripts, but in the general case you might want the script to handle the error instead of dying.

Oops! So used to "if!" or "or" to catch errors. Fixed. As for the simplicity, it was just an example. You're right that it's really not suitable for use. The docs for `system` provide a more complete example.	[reply] [d/l]
