/bin/ls does this for the user, group, and size columns. Note that this only works if you batch up your output (or take two passes over your input data). I seem to remember /usr/bin/find doing this dynamically by expanding columns as it saw values that were larger than the previous max, but apparently not (I just tested it). -- Dan Nelson dnel...@allantgroup.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
