Sh DESCRIPTION
Nm
is a filter that allows the viewing of files compressed with Lempel-Ziv
encoding.
Such files generally have a
Dq Z
or
Dq gz
extension (both the
Xr compress 1
and
Xr gzip 1
formats are supported).
Any
Ar flags
that are specified are passed to the user's preferred
Ev PAGER
(which is
Pa /usr/bin/more
by default).
Pp
Nm zless
is equivalent to
Nm zmore
but uses
Xr less 1
as a pager instead of
Xr more 1 .
Pp
When multiple files are specified,
Nm
will pause at the end of each file and present the following prompt to the user:
Bd -literal -offset indent
prev_file (END) - Next: next_file
Ed
Pp
Where
Sy prev_file
is the file that was just displayed and
Sy next_file
is the next file to be displayed.
The following keys are recognized at the prompt:
Bl -tag -width "e or q" -offset indent
It Ic e No or Ic q
quit
Nm zmore .
It Ic s
skip the next file (or exit if the next file is the last).
El
Pp
If no files are specified,
Nm
will read from the standard input.
In this mode
Nm
will assume
Xr gzip 1
style compression since there is no suffix on which to make a decision.
Sh ENVIRONMENT
Bl -tag -width "PAGER"
It Ev PAGER
Program used to display files.
If unset,
Pa /usr/bin/more
is used
Pq Nm zmore
