If I use a pipe then I get the prompt as well as the result as part of the return value. Using a here document doesn't return the prompt.	[reply]

What qx is doing is calling the shell perl -V:sh, and shell usually doesn't like newlines (which is apparently why in bash you use heredoc), so you have to quote/escape/encode/serialize those args, for which you can use String::ShellQuote ( or Win32::ShellQuote ) Or use IPC::Run3, its not backticks but it handles quoting for you Or use IPC::System::Simple capturex, its close to backticks, and it can handles quoting for you	[reply]

You could, of course, accept "the prompt as well as the result as part of the return value" and then remove the prompt -- with the likes of `=~ s///;`, among other possibilities.	[reply] [d/l]
