I already told you this in the chatterbox. It's easiest is to redirect the output. Many shells allow you to capture the error output via `2> errorlog` [download] . Or call your program via my @output = `$program 2>&1` [download] Otherwise, look at IPC::Run.	[reply] [d/l] [select]

In addition, check the value of $? after the system call. It contains a processed value of the exit code of the program (divide by 256 and you'll get very close), it'll be non-zero if there was an error.	[reply]
