      NAME
           more, page - peruse a file on the screen

      SYNTAX
           more [ -cdflsu ] [ -n ] [ +linenumber ] [ +/pattern ] [ name
           ...  ]

           page more options

      DESCRIPTION
           More is a filter which allows examination of a continuous
           text one screenful at a time on a soft-copy terminal.  It
           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 presses the
           keyboard space-bar, another screenful is displayed.  Other
           possibilities are enumerated later.

           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 "Hit space
                to continue, Rubout to abort" at the end of each
                screenful.  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, rather than screen
                lines.  That is, long lines are not folded.  This
                option is recommended if nroff output is being piped
                through ul, since the latter may generate 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.

           -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.

      MORE(1)                     (bsd 4.1)                     MORE(1)



           -s   Squeeze multiple blank lines from the output, producing
                only one blank line.  Especially helpful when viewing
                nroff output, this option maximizes the useful
                information present on the screen.

           -u   Normally, more will handle underlining such as produced
                by nroff 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 the screen is
           cleared before each screenful is printed (but only if a full
           screenful is being printed), and k - 1 rather than k - 2
           lines are printed in each screenful, where k is the number
           of lines the terminal can display.

           More 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.

           More 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 would
           cause all invocations of more , including invocations by
           programs such as man and msgs , to use this mode.  Normally,
           the user will place the command sequence which sets up the
           MORE environment variable in the .cshrc or .profile file.

           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.

           Other sequences which may be typed when more pauses, and
           their effects, are as follows (i is an optional integer
           argument, defaulting to 1) :

           i<space>
                display i more lines, (or another screenful if no
                argument is given)

      MORE(1)                     (bsd 4.1)                     MORE(1)



           ^D   display 11 more lines (a ``scroll'').  If i is given,
                then the scroll size is set to i.

           d    same as ^D (control-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

           q or Q
                Exit from more.

           =    Display the current line number.

           v    Start up the editor vi at the current line.

           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 there are less than i occurrences
                of expr, and the input is a file (rather than a pipe),
                then the position in the file remains unchanged.
                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 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.

           !command
                invoke 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  skip to the i-th next file given in the command line
                (skips to last file if n doesn't make sense)

      MORE(1)                     (bsd 4.1)                     MORE(1)



           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, then 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 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 press RETURN.  Up to the time when the command
           character itself is given, the user may press the line-kill
           character to cancel the numerical argument being formed.  In
           addition, use 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 control-\).  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 teletype, then more acts
           just like cat, except that a header is printed before each
           file (if there is more than one).

           A sample usage of more in previewing nroff output would be

                nroff -ms +2 doc.n | more -s
