in reply to (code) One-liner removes whitespace-only lines from text file


This is attributable to abigail:      perl -lp00ee file

Update: As chip points out, this one-liner removes blank lines and not whitespace-only lines.

    Well, 10 out of 10 for cleverness, but abigail's trick only removes empty lines, i.e. those that match /^$/; but the original requirement was to remove lines made up of any combination of whitespace.
