not shure about NT, depends on your perl version if it understands backticks.
2>&1 is the (UNIX)sh notation for redirecting STDERR to STDOUT. There is something similar for NT's cmd.exe, can't remeber how it works there (it's far to long ago since I trashed all M$ systems:-)

I gave 2 suggestions, 1'st for the original question, and 2'nd for the additional question.
Both work for me (in my environment), so I don't see a reason why to delete this question.

"..so I don't see a reason why to delete this question. ..."

Both these comments will not work on a Win* environment.

As ItsMe has indicated, he/she is on an NT environment.

The purpose of posting our comments is to help the user get a solution that would work in their environment too. Since ItsMe has not indicated the same, i am certain that he/she has not found the solution she/he was looking for.

Therefore, my recommendation to delete.

Hmm, I know of WinNT where it works: for example with ActivePerl or cygwin.

ItsMe just stated that it does not for her/him, but never returned with more comments.
Even if it ends up in "not working for (Its)Me", I'd like to make it a 0 pts PAQ, instead of deleting.

"..I'd like to make it a 0 pts PAQ,.."

A 0 pts PAQ is fine with me.
