Yes, there are lots. The one you choose does rather depend on whether
or not you want to look at the return code or stderr of the external
program, or if you want to get a lot of data out, which you need to
buffer and, of course, if you need to pump it in.

The most simple way to do it is:

$var = `command`; # those are back ticks
