--- Comment #12 from Ed Maste <ema...@freebsd.org> --- (In reply to David Schlachter from comment #3) > printf "\n\n\n\n" | sed "/^\s*$/d" Note that this is not actually testing \s since we're matching 0 or more. For example, try (on 12.x or earlier): $ printf "\n\n\n\n" | sed "/^x*$/d" This also deletes the blank lines. Or, try: $ printf " \n \n \n \n" | sed "/^\s*$/d" and observe that the except-for-whitespace empty lines are not stripped. -- You are receiving this mail because: You are the assignee for the bug.
