that's what exec() is for. $command need to contain a *local* path to the command in question, currently your trying to pass a url to bash ... which obviously doesn't do much. the shell script in question needs to have the executable bit set in order to run (either that or change to command to run bash with your script as an argument) I'd also suggest putting the shell script outside of your webroot, or at least in a directory that's not accessable from the web. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
