MORE(1) User Commands MORE(1)

NAME
more - file perusal filter for crt viewing

SYNOPSIS
more [options] file ...

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.

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.

COMMANDS
Interactive commands for more are based on vi(1). Some commands may be preceded by a
decimal number, called k in the descriptions below. In the following descriptions, ^X
means control-X.

h or ?
Help; display a summary of these commands. If you forget all other commands,
remember this one.

SPACE
Display next k lines of text. Defaults to current screen size.

z
Display next k lines of text. Defaults to current screen size. Argument becomes
new default.

RETURN
Display next k lines of text. Defaults to 1. Argument becomes new default.

d or ^D
Scroll k lines. Default is current scroll size, initially 11. Argument becomes
new default.

q or Q or INTERRUPT
Exit.

s
Skip forward k lines of text. Defaults to 1.

f
Skip forward k screenfuls of text. Defaults to 1.

b or ^B
Skip backwards k screenfuls of text. Defaults to 1. Only works with files, not
pipes.

'
Go to the place where the last search started.

=
Display current line number.

/pattern
Search for kth occurrence of regular expression. Defaults to 1.

n
Search for kth occurrence of last regular expression. Defaults to 1.

!command or :!command

variable VISUAL if defined, or EDITOR if VISUAL is not defined, or defaults to
vi(1) if neither VISUAL nor EDITOR is defined.

^L

:n
Go to kth next file. Defaults to 1.

:p
Go to kth previous file. Defaults to 1.

:f

ENVIRONMENT
The more command respects the following environment variables, if they exist:

MORE
This variable may be set with favored options to more.

SHELL
Current shell in use (normally set by the shell at login time).

TERM
The terminal type used by more to get the terminal characteristics necessary to
manipulate the screen.

VISUAL
The editor the user prefers. Invoked when command key v is pressed.

EDITOR
The editor of choice when VISUAL is not specified.

HISTORY
The more command appeared in 3.0BSD. This man page documents more version 5.19
(Berkeley 6/29/88), which is currently in use in the Linux community. Documentation
was produced using several other versions of the man page, and extensive inspection
of the source code.
