    NAME
         more, page - file perusal filter for crt viewing

    SYNOPSIS
         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 hits a
         space, 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 "Press space
    	  to continue, 'q' to quit." at the end of each screen-
    	  ful, 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, 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 con-
    	  tains 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.

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

         -u   Normally, more will handle underlining such as produced
    	  by nroff in a manner appropriate to the particular ter-
    	  minal:  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 regu-
    	  lar 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 argu-
    	  ment is given)

         ^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

         ib   skip back i screenfuls and print a screenful of lines

         i^B  same as b

         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 com-
    	  mands.

         i/expr
    	  search for the i-th occurrence of the regular expres-
    	  sion 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.  Oth-
    	  erwise, 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)

         i:p  skip to the i-th previous file given in the command
    	  line.  If this command is given in the middle of print-
    	  ing 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 neces-
         sary to type a carriage return.  Up to the time when the
         command character itself is given, the user may hit the line
         kill character to cancel the numerical argument being
         formed.  In addition, the user may hit the erase character
         to redisplay the --More--(xx%) message.

         At any time when output is being sent to the terminal, the
         user can hit 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 wait-
         ing 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
