try system or backticks. They block until the called program completes. Backtick (which are ` as opposed to ') return a string of what was sent to STDOUT by the program. Try $bin = `ls /usr/bin`; to test it out. BTW. `$?` holds any error if the called program fails. Ira, "So... What do all these little arrows mean?" ~unknown	[reply] [d/l] [select]

To run a command line program use `system()` `system("wzzip -yp temp.zip file.txt");` [download] To get the output of a command use `` (backticks) $output = `wzzip -yp temp.zip file.txt`; [download] These are the two most common ways to run command line programs (and most other programs for that matter).
