Name
       more, page - display file data at your terminal

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

       page more options

Description
       The filter allows you to examine a file one screenful of text 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
       space bar, another screenful is displayed.

Options
       +linenumber Start up at linenumber.

       +/pattern   Start  up  two lines before the line containing the regular
		   expression pattern.	The command line options are:

       -c	   Begins each page at the top of the screen and  erases  each
		   line just before it draws on it.  This avoids scrolling the
		   screen, making it easier to read while  is  writing.	  This
		   option is ignored if the terminal does not have the ability
		   to clear to the end of a line.

       -d	   Displays extended continuation prompt at end of  each  dis‐
		   play.  The command prompts the user with the message "Press
		   space to continue, ´q´ to quit." at the end of each screen‐
		   ful,	 and  responds	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	   Counts logical text lines (does not fold long lines).  This
		   option is recommended if  output  is	 being	piped  through
		   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	 may  think  that  lines are longer than they actually
		   are, and fold lines erroneously.

       -l	   Ignores line feeds (CTRL/Ls) and normally, pauses  at  line
		   feeds.   If this option is not given, pauses 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 is cleared before the file is printed.

       -n	   Specifies number of line displays.

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

       -u	   Ignores  all	 underlining in the data.  If the terminal can
		   perform underlining or has a stand-out mode, outputs appro‐
		   priate  escape sequences to enable underlining or stand-out
		   mode for underlined information in the source file.	The -u
		   option suppresses this processing.

       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 screen‐
       ful, where k is the number of lines the terminal can display.

       The command looks in the file /etc/termcap to determine terminal	 char‐
       acteristics,  and  to determine the default window size.	 On a terminal
       capable of displaying 24 lines, the default window size is 22 lines.

       The command looks in the environment variable MORE to pre-set any flags
       desired.	 It scans the arguments defined in variable MORE, the same way
       it works on command line.  For example, if you  prefer  to  view	 files
       using  the -c mode of operation, the command setenv MORE -c or the com‐
       mand sequence MORE='-c' ; export MORE would cause  all  invocations  of
       including  invocations  by programs such as and to use this mode.  Nor‐
       mally, the user places the command sequence  which  sets	 up  the  MORE
       environment variable in the .cshrc or .profile file.

       If  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 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)

       ^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 or i^B   Skip back i screenfuls and print a screenful of lines

       q or Q	   Exit from more.

       =	   Display the current line number.

       v	   Start up the editor at the current line.

       h or ?	   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.   of  the
		   last regular expression entered.

       in	   Search for the i-th occurrence

       '	   (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 cur‐
		   rent 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 printing out a
		   file, then goes back to the beginning of  the  file.	 If  i
		   doesn't  make  sense,  skips back to the first file.	 If 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

       .	   (dot) Repeat the previous command.

       The  commands  take effect immediately, that is, it is not necessary 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-\).  The 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, 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 not show on your terminal, except for
       the / and !  commands.

       If the standard output is not a teletype, then acts  just  like	except
       that a header is printed before each file (if there is more than one).

       A sample usage of in previewing output would be
       nroff -ms doc.n | more -s
