If you're using the bash shell something like this might work:

if (fork()){

}
else
{
 exec 'com1 | com2; exit $PIPESTATUS[0]';
}

You can read more about this in the bash manual.

Thanks for the replies I had read about the PIPESTATUS variable in bash ..... for some reason I thought that a perl exec would always run in 'sh'. It does on my system. Apologies if this is a very basic question, but can I change that so that it does run in a bash shell?	[reply]

On my system, /bin/sh runs bash. But you could specify which shell you want. `exec(bash => (-c => 'com1 \| com2; exit $PIPESTATUS[0]'));` [download]	[reply] [d/l]
