NAME
more, page - display file one screenful at a time
SYNOPSIS
more [ -cdflpsu ] [ -n ] [ +linenumber ] [ +/pattern ] [ name ... ]
page [ more options ]
DESCRIPTION
More is a filter that allows you to examine a long text one CRT-
screenful at a time. It 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 types a
space, another screenful is displayed. Other possibilities are
listed below in the Commands section.
Options
The command line options are:
-n An integer which is the size (in lines) of the window which
more will use instead of the default.
-c More will draw each page by beginning at the top of the screen
and erasing each line just before it draws on it. This avoids
scrolling the screen, making it easier to read while more is
writing. This option will be ignored if the terminal does not
have the ability to clear to the end of a line.
-d More will prompt the user with the message "Press space to
continue, 'q' to quit." at the end of each screenful, and will
respond to subsequent illegal user input by printing "Press
'h' for instructions." instead of ringing the bell. This is
useful if more is being used as a filter in some setting, such
as a class, where many users may be unsophisticated.
-f This causes more to count logical lines, rather than screen
lines. That is, long lines are not folded. This option is
recommended for viewing ul(1) output, since it may contain
escape sequences. These escape sequences contain characters
which would ordinarily occupy screen positions, but which do
not print when they are sent to the terminal as part of an
escape sequence. Thus more may think that lines are longer
than they actually are, and fold lines erroneously. This
option is also recommended when piping man output through
more; otherwise, more may become confused by nonprinting video
attribute characters typically displayed to a terminal screen.
-l Do not treat ^L (form feed) specially. If this option is not
given, more will pause after any line that contains a ^L, as
if the end of a screenful had been reached. Also, if a file
begins with a form feed, the screen will be cleared before the
file is printed.
-p Clear the screen before each screenful is printed (but only if
a full screenful is being printed), and print k - 1 rather
than k - 2 lines in each screenful, where k is the number of
lines the terminal can display.
-s Squeeze multiple blank lines from the output, producing only
one blank line. Especially helpful when viewing formatted
text, this option maximizes the useful information present on
the screen.
-u Normally, more will handle underlining in a manner appropriate
to the particular terminal: if the terminal can perform
underlining or has a stand-out mode, more will output
appropriate escape sequences to enable underlining or stand-
out mode for underlined information in the source file. The
-u option suppresses this processing.
+linenumber
Start up at linenumber.
+/pattern
Start up two lines before the line containing the regular
expression pattern.
If the program is invoked as page, then it behaves the same as more
with the -p option.
More accesses the terminfo(4) database to determine terminal
characteristics such as the screen size, and to determine the default
window and scroll sizes. On a terminal with no fixed number of rows,
such as a hardcopy printer, the screen size defaults to 24 lines.
The default window size is normally two less than the screen size.
However, if the -p option is specified or the program is invoked as
page, the window size defaults to one less than the length of the
screen. The scroll size defaults to half the window size.
More looks in the environment variable MORE to preset 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 would cause all invocations of more
to use this mode. Normally, the user will place the command sequence
which sets up the MORE environment variable in the .login or .profile
file (see profile(4)).
If more is reading from a file, rather than a pipe, then 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.
Commands
Other sequences that may be typed when more pauses, and their
effects, are as follows (i is an optional integer argument,
defaulting to 1 unless otherwise noted):
ispace Display i more lines, or another screenful if no argument is
given.
id Display i more lines (a ``scroll''). If i is given, then the
scroll size is set to i. Otherwise, the default is to scroll
11 lines.
i^D (control-D)
Same as d.
iz Same as typing a space except that i, if present, becomes the
new window size.
is Skip i lines and print a screenful of lines.
if Skip i screenfuls and print a screenful of lines.
ib Skip back i screenfuls and print a screenful of lines. This
command works only when the input is a file, not a pipe.
i^B (control-B)
Same as b.
q or Q Exit from more.
= Display the current line number.
v Start up the editor vi(1) at the current line. This command
works only when the input is a file, not a pipe.
h Help command; give a description of all the more commands.
i/expr Search for the i-th occurrence of the regular expression expr.
If the search is successful a screenful is displayed, starting
two lines before the place where the expression was found.
Otherwise, if the input is a file, the position in the file
remains unchanged; if the input is a pipe, more terminates.
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 Search for the i-th occurrence of the last regular expression
entered.
' (single quote)
Go 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. This command works
only when the input is a file, not a pipe.
!command
Invoke a shell and execute 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 Skip to the i-th next file given in the command line. If i
doesn't make sense, skip to the last file.
i:p Skip 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 counts the current file when doing the skipping. If i
doesn't make sense, more skips back to the first file. If
more is not reading from a file, the terminal bell is rung and
nothing else happens.
:f Display the current file name and line number.
:q or :Q
Exit from more (same as q or Q).
. (dot)
Repeat the previous 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 type the line kill character to cancel
the numerical argument being formed. In addition, the user may type
the erase character to redisplay the --More--(xx%) message.
At any time when output is being sent to the terminal, the user can
type the quit character (normally control-\) to interrupt the
display. more will stop sending output, and will display 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, 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 noecho 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 ! commands.
If the standard output is not a tty device then more acts just like
cat, except that a header is printed before each file if there is
more than one.
EXAMPLES
$ more textfile
Display the contents of the file "textfile" using the more processor.
This allows for display of the file "textfile" on a screen by screen
basis.
$ man more | more -f
Prints the manual page for the more command and pipes the output to
the more processor. This allows for display of the more
documentation on a screen by screen basis. The -f option ensures
that more will display the output of the man(1) command correctly,
since man generates escape sequences.
$ ls -l | more
Display all information about the files in the current working
directory and pipes the output to the more processor. This allows
for display of the directory listing on a screen by screen basis.

BUGS
Skipping backwards is too slow on large files.
