is a filter which allows examination of compressed or plain text files
one screenful at a time on a soft-copy terminal.
works on files compressed with
and also on uncompressed files.
If a file does not exist,
looks for a file of the same name with the addition of a .gz, .z or .Z suffix.
normally pauses after each screenful, printing –More–
at the bottom of the screen.
If the user then types a carriage return, one more line is displayed.
If the user hits a space,
another screenful is displayed. Other possibilities are enumerated later.

to determine terminal characteristics,
and to determine the default window size.
On a terminal capable of displaying 24 lines,
the default window size is 22 lines.
To use a pager other than the default

Other sequences which may be typed when

argument, defaulting to 1) :

Otherwise, a screenful is displayed, starting two lines before the place
where the expression was found.
The user’s erase and kill characters may be used to edit the regular
Erasing back past the first column cancels the search command.
The commands take effect immediately, i.e., it is not necessary to
type a carriage return.
Up to the time when the command character itself is given,
the user may hit the line kill character to cancel the numerical
argument being formed.
In addition, the user may hit the erase character to redisplay the

The user may then enter one of the above commands in the normal manner.
Unfortunately, some output is lost when this is done, due to the
fact that any characters waiting in the terminal’s output queue
are flushed when the quit signal occurs.
The terminal is set to
mode by this program so that the output can be continuous.
What you type will thus not show on your terminal, except for the / and !
If the standard output is not a teletype, then
acts just like
