That's assuming user input is used to build the command string. If the command is hardcoded, or if interpolated data is well validated (matches `/^\w+\z/`, for example), there's no problem.	[reply] [d/l]

The cgi code wants to "run" an external process and capture its output for processing. BTW - it's an intranet application; security is not a concern. How can I achieve this without backticks? Thanks.	[reply]

cseelig, "BTW - it's an intranet application; security is not a concern." Yikes! IMHO security should always be a concern. Check out CGI Programming FAQ under Security for some interesting reading. Update: Also merlyn has a great article on the subject of security which I would advise reading. Martin	[reply]

Ok. So how would you do it? (Where "it" is to have a Perl cgi script invoke an external executable and capture the results for subsequent processing.)	[reply]

Have you tried supplying the full path to the exe? my $output = `c:/path/to/program.exe`; [download]	[reply] [d/l]
