Running other programs from perl using `someprogram`

[LucL]

Ok,

So something like my @mfiles=`ls` will run the LS command and populate mfiles array with the files.

But for some reason when I run a different command the other linux application always outputs to the screen and I cannot capture it using $t1=`linuxprogram`

Is there any way to run and capture the output of a program into a perl variable? I know there must be a fairly simple way but I can't figure it out. The output is just a few lines of text but with this program it always goes to the screen.

Thanks!
Luc L.

It *may* be that the program is writing to stderr, so you can try this:

$t1=`linuxprogram 2>&1`

alternatively, you can use a pipe to do this, like:

open(X, "linuxprogram 2>&1 |"); 
print while (<X>);
close(X);
