Seems like you might want to post these types of things to
[EMAIL PROTECTED] as they don't have a lot to do with CGI.
'system' returns a combination of exit values from the command. The 0
indicates that the command was successful.
perldoc -f system
For more on parsing return values.
Since you are looking for the output from the command you should
consider using backticks also known as the qx operator,
perldoc perlop (search for qx)
Additionally you may want to read through,
perldoc perlipc
perldoc IPC::Open3
If you are still stuck as it introduces Open3/Open2, etc.
Point your additional questions to the beginners group, lots of people
there ready to help.
