in reply to Put your inplace-edit backup files into a subdir

I've had more than one person write to me in the day since I posted this snippet to say "Randal, you forgot the -i! It's not an in-place edit without that!".

No, I didn't. Setting $^I is the programmatic equivalent to setting -i on the command-line.

Cool, eh?

    I was personally puzzled at what $^T is for a moment, though I knew about $^I. So the simple form would be
    mkdir bak/ ; perl -pi'bak/*' -e 's/foo/bar/g' file1 file2 file3 ...
    Or
    perl -pi'bak/*' -e 'BEGIN { mkdir($^I =~ m!(.*/)!) } s/foo/bar/g' file +1 file2 file3 ...
    Or maybe even
    perl -MFile::Path -pi'bak/*' -e 'BEGIN { mkpath [ $^I =~ m!(.*/)! ] } +s/foo/bar/g' file1 file2 file3 ...
    *grin*
