DESCRIPTION
The more command is a filter that allows examination of a continuous text, one
screen at a time. The program normally pauses after each screen and displays
the word "more" at the bottom of the screen. If the user then types a carriage
return, one more line is displayed. Pressing the space bar displays another
screen of information.
If the program is invoked as page, the screen is cleared before each screen is
printed (but only if a full screen is being printed), and k-1 rather than k-2
lines are printed in each screen, where k is the number of lines the terminal
can display.
The more command looks in the file /etc/termcap 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.
The more command looks in the environment variable MORE to pre-set any flags
desired. For example, if you prefer to view files using the -c mode of
operation, the csh command setenv more -c or the sh command sequence more='-c';
export more causes all invocations of the more command including invocations by
such programs as man to use this mode. Normally, the user places the command
sequence which sets up the MORE environment variable in the cshrc or .profile
file.

If the more command is reading from a file, rather than a pipe, a percentage is
displayed along with the "--More" prompt. This gives the fraction of the file
(in characters, not lines) that has been read so far.
FLAGS
-n Determines the size (in lines) of the window, where -n is an integer.
-c Draws each page by beginning at the top of the screen by erasing each
line just before the more command draws on it. This avoids scrolling
the screen and makes it easier to read while the command is writing.
This option is ignored if the terminal does not have the ability to
clear to the end of a line.
-d Prints messages for novice users.
-f Causes more to count logical lines rather than screen lines. That is,
long lines are not folded. This option is useful if nroff output is
being piped through ul since ul may generate escape sequences. These
escape sequences contain characters which would ordinarily occupy
screen positions but do not print. Thus, more may think that lines are
longer than they actually are and fold line erroneously.
-l Ignores a form feed (ctrl-L); that is, more does not pause after any
line that contains a Ctrl-L and does not clear the screen if a file
begins with a Ctrl-L.
-p Clear the screen before displaying a new screen.
-s Removes multiple blank lines from the output, producing only one blank
line. This options is useful when viewing nroff output, maximizing the
amount of useful information that can be viewed on the screen.
-u Normally, more handles underlining produced by nroff in a manner
appropriate to the particular terminal. If the terminal can perform
underlining or has a stand-out mode, more outputs the appropriate
escape sequences to enable underlining or stand-out mode for underlined
information in the source file. The -u option suppresses this
processing.
+linenumber
Starts up at linenumber.
+/pattern
Starts up two lines before the line containing the regular expression
pattern.
Other sequences which may be typed when More pauses, and their effects, follow
(i is an optional integer argument, defaulting to 1 (the numeral 1)):

i<space>
Displays i more lines (or another screen if no argument is given). If
stty speed is set to less than 1200 baud, you must follow i<space> with
a <CR> (carriage return).
Ctrl-B Scrolls backward one screen.
b Scrolls backward one screen. Same as Ctrl-B.
Ctrl-D Displays 11 more lines (a "scroll"). If i is given, the scroll size is
set to i.
d Same as Ctrl-D.
i z Same as typing a space except that i, if present, becomes the new
window size.
i s Skips i lines and prints a screenful of lines.
i f Skips i screenfuls and prints a screenful of lines.
q or Q Exits from more.
= Displays the current line number.
v Starts up the editor vi at the current line.
h Help commands; gives a description of all the more commands.
i/expr Searches for the i-th occurrence of the regular expression expr. If
there are less than i occurrences of expr and the output is a file
(rather than a pipe), the position in the file remains unchanged.
Otherwise, a screenful is displayed, starting two lines before the
place where the expression is found. The user's erase and kill
characters may be used to edit the regular expression. Erasing back
past the first column cancels the search command.
in Searches for the i-th occurrence of the last regular expression
entered.
Ctrl-L Redraws the screen.
' (Single quote.) Goes to the point from which the last search started.
If no search has been performed in the current file, this command goes
back to the beginning of the file.
!command
Invokes a shell with command. The characters "%" and "!" in command
are replaced with the current file name and the previous shell command,
respectively. If there is no current file name, "%" is not expanded.
The sequences "\%" and "\!" are replaced by "%" and "!", respectively.

i:n Skips to the i-th next file given in the command line (skips to the
last file as n does not make sense).
i:p Skips to the i-th previous file given in the command line. If this
command is given in the middle of printing out a file, more goes back
to the beginning of the file. If i doesn't make sense, more skips back
to the first file. If more is not reading from a file, the bell rings
and nothing else happens.
:f Displays the current file name and line number.
:q or :Q
Exits from more (same as q or Q).
. (dot) Repeats the previous command.
The commands take effect immediately. For example, it is not necessary to type
a carriage return. Up to the time when the command character itself is given,
the user may enter the line kill character to cancel the numerical argument
being formed. In addition, the user may enter the erase character to redisplay
the "--More--(xx%)" message.
At any time when output is being sent to the terminal, the user can press the
quit key (normally Ctrl-\). The more command stops sending output and displays
the usual "--More--" prompt. The user may then enter one of the above commands
in the normal manner. Unfortunately, some output is lost when this is done,
because any characters waiting in the terminal's output queue are flushed when
the quit signal occurs.
The terminal is set to noecho mode by this program so that the output can be
continuous. What you type, therefore, does not show on the terminal, except
for the / and ! commands.
If the standard output is not a teletype, more acts just like cat, except that
a header is printed before each file (if there is more than one).
