The easy way to do external calls is using backticks. You could easily add the STDERR redirect (2>&1) to your command if you need to capture STDERR; otherwise it just interleaves the child's STDERR with the parent program's STDERR. As soon as you actually want to keep the various streams separate, I usually jump to IPC::Open3 or a full blown pipe/fork/exec as described in perlipc. There are popular wrappers out there that are supposed to handle this, e.g. Capture::Tiny, but I haven't gotten much utility from them.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
