zless − file perusal filter for crt viewing of compressed

zless [ name ...  ]

Zless is a filter which allows examination of compressed or
plain text files one screenful at a time on a soft‐copy
terminal.  It is the equivalent of setting the environment
variable PAGER to less, and then running zmore.  However,
enough people seem to think that having the command zless
available is important to be worth providing it.
