Синопсис (Synopsis)
more [options] file ...
Описание (Description)
more is a filter for paging through text one screenful at a time.
This version is especially primitive. Users should realize that
less(1) provides more(1) emulation plus extensive enhancements.
Параметры (Options)
Options are also taken from the environment variable MORE (make
sure to precede them with a dash (-)) but command-line options
will override those.
-d, --silent
Prompt with "[Press space to continue, 'q' to quit.]", and
display "[Press 'h' for instructions.]" instead of ringing
the bell when an illegal key is pressed.
-l, --logical
Do not pause after any line containing a ^L (form feed).
-f, --no-pause
Count logical lines, rather than screen lines (i.e., long
lines are not folded).
-p, --print-over
Do not scroll. Instead, clear the whole screen and then
display the text. Notice that this option is switched on
automatically if the executable is named page.
-c, --clean-print
Do not scroll. Instead, paint each screen from the top,
clearing the remainder of each line as it is displayed.
-s, --squeeze
Squeeze multiple blank lines into one.
-u, --plain
Suppress underlining. This option is silently ignored as
backwards compatibility.
-n, --lines number
Specify the number of lines per screenful. The number
argument is a positive decimal integer. The --lines option
shall override any values obtained from any other source,
such as number of lines reported by terminal.
-number
A numeric option means the same as --lines option argument.
+number
Start displaying each file at line number.
+/string
The string to be searched in each file before starting to
display it.
--help
Display help text and exit.
-V, --version
Display version information and exit.
Команды (Commands)

may be preceded by a decimal number, called k in the descriptions

versions of the man page, and extensive inspection of the source
code.
