Thanks Antonio! --colour and -NUM are not necessary. If I find them being used I'll change them. The --silent and -P option are used a lot.

I generally dislike implementing spelling variations, but this one is specially confusing because GNU grep does accept an environment variable named GREP_COLORS but none named GREP_COLOURS. > others are > > -G --basic-regexp > -U --binary > -u --unix-byte-offsets '-u, --unix-byte-offsets' is going to be removed next year from GNU grep: https://git.savannah.gnu.org/cgit/grep.git/plain/src/grep.c case 'u': /* Obsolete option; it had no effect; FIXME: remove in 2023 */ error (0, 0, _("warning: --unix-byte-offsets (-u) is obsolete")); break; > -T --initial-tab > -NUM I don't see how -NUM can be implemented while respecting the syntax of command line arguments[1] where '-23' would mean '-C2 -C3', not '-C23'. I would recommend to use -C instead of the non-standard grep "option" -NUM.

I'll release a new version of zutils with the new options ASAP (in a few days). Best regards, Antonio.
