Top Forums Shell Programming and Scripting how to invoke external program and capture its output Post 302681489 by Corona688 on Friday 3rd of August 2012 12:45:03 PM

Running 30,000 individual, separate shells to run 30,000 commands is wrong, period. That's like making 300 phonecalls to say 300 words. You never have to do that, even if you're processing the result in perl. There's also some useless use of backticks in there, though seeing it in perl is a first.

You could do the loop in shell and feed the result into perl through files or stdin, perhaps.

I don't know why it's taking 80 as a command. It shouldn't be, unless there's odd unprintable characters there which convince it it's on a different line. Or maybe a ; Did you copy-paste the code literally or is it slightly different from what you posted?
