On the other hand: $ printf 'abc def' | grep -o '\b[a-z]' $ printf 'abc def' | grep -o '\<[a-z]' will each match against all six of the letters. Matching against the patterns: '[a-z]\b' '[a-z]\>' '[a-z]$' gives correct results. -- dubious...@gmail.com _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
