Is there any case or reason to use "more" unix command instead of "less". As far as I see "less" is "better" in all senses, so does it mean that "more" is a command which has no reason to be used when there's "less"?
more command is considerably older than the
less command (1978 vs 1983ish). The
less command was introduced as a 'backwards more' (because you could scroll up). The
more command is part of the OS binaries with most modern unix/linux OSs, while
less is maintained externally as an open source project.
I'll often use
more on systems with the bare minimum OS installed because
less isn't available or installed yet.
