Hello, it doesn't harm but I always stumple when I read the SYNOPSIS in grep's man page where - in contrast to the usage message - the dots and the closing are in the wrong order compared to "all" other man pages:
$ man grep | head GREP(1) User Commands GREP(1) NAME grep, egrep, fgrep, rgrep - print lines that match patterns SYNOPSIS grep [OPTION...] PATTERNS [FILE...] grep [OPTION...] -e PATTERNS ... [FILE...] grep [OPTION...] -f PATTERN_FILE ... [FILE...] $ grep Usage: grep [OPTION]... PATTERNS [FILE]... Try 'grep --help' for more information. Best regards Martin
