NAME
     more — file perusal filter for crt viewing

SYNOPSIS
     more [-ceinus] [-t tag] [-x tabs] [-/ pattern] [-#] [file ...]

DESCRIPTION
     More is a filter for paging through text one screenful at a time.	It
     uses termcap(3) so it can run on a variety of terminals.  There is even
     limited support for hardcopy terminals.  (On a hardcopy terminal, lines
     which should be printed at the top of the screen are prefixed with an up-
     arrow.)  File may be a single dash (``-''), implying stdin.

OPTIONS
     Command line options are described below.	Options are also taken from
     the environment variable MORE (make sure to precede them with a dash
     (``-'')) but command line options will override them.

     -c	   Normally, more will repaint the screen by scrolling from the bottom
	   of the screen.  If the -c option is set, when more needs to change
	   the entire display, it will paint from the top line down.

     -e	   Normally, if displaying a single file, more exits as soon as it
	   reaches end-of-file.	 The -e option tells more to exit if it
	   reaches end-of-file twice without an intervening operation.	If the
	   file is shorter than a single screen more will exit at end-of-file
	   regardless.

     -i	   The -i option causes searches to ignore case; that is, uppercase
	   and lowercase are considered identical.

     -n	   The -n flag suppresses line numbers.	 The default (to use line num‐
	   bers) may cause more to run more slowly in some cases, especially
	   with a very large input file.  Suppressing line numbers with the -n
	   flag will avoid this problem.  Using line numbers means: the line
	   number will be displayed in the = command, and the v command will
	   pass the current line number to the editor.

     -s	   The -s option causes consecutive blank lines to be squeezed into a
	   single blank line.

     -t	   The -t option, followed immediately by a tag, will edit the file
	   containing that tag.	 For more information, see the ctags(1) com‐
	   mand.

     -u	   By default, more treats backspaces and CR-LF sequences specially.
	   Backspaces which appear adjacent to an underscore character are
	   displayed as underlined text.  Backspaces which appear between two
	   identical characters are displayed as emboldened text.  CR-LF
	   sequences are compressed to a single linefeed character.  The -u
	   option causes backspaces to always be displayed as control charac‐
	   ters, i.e. as the two character sequence ``^H'', and CR-LF to be
	   left alone.

     -x	   The -x option sets tab stops every N positions. The default for N
	   is 8.

     -/	   The -/ option specifies a string that will be searched for before
	   each file is displayed.

COMMANDS
     Interactive commands for more are based on vi(1).	Some commands may be
     preceded by a decimal number, called N in the descriptions below.	In the
     following descriptions, ^X means control-X.

     h		 Help: display a summary of these commands.  If you forget all
		 the other commands, remember this one.

     SPACE or f or ^F
		 Scroll forward N lines, default one window.  If N is more
		 than the screen size, only the final screenful is displayed.

     b or ^B	 Scroll backward N lines, default one window (see option -z
		 below).  If N is more than the screen size, only the final
		 screenful is displayed.

     j or RETURN
		 Scroll forward N lines, default 1.  The entire N lines are
		 displayed, even if N is more than the screen size.

     k		 Scroll backward N lines, default 1.  The entire N lines are
		 displayed, even if N is more than the screen size.

     d or ^D	 Scroll forward N lines, default one half of the screen size.
		 If N is specified, it becomes the new default for subsequent
		 d and u commands.

     u or ^U	 Scroll backward N lines, default one half of the screen size.
		 If N is specified, it becomes the new default for subsequent
		 d and u commands.

     g		 Go to line N in the file, default 1 (beginning of file).

     G		 Go to line N in the file, default the end of the file.

     p or %	 Go to a position N percent into the file.  N should be
		 between 0 and 100.  (This works if standard input is being
		 read, but only if more has already read to the end of the
		 file.	It is always fast, but not always useful.)

     r or ^L	 Repaint the screen.

     R		 Repaint the screen, discarding any buffered input.  Useful if
		 the file is changing while it is being viewed.

     m		 Followed by any lowercase letter, marks the current position
		 with that letter.

     '		 (Single quote.)  Followed by any lowercase letter, returns to
		 the position which was previously marked with that letter.
		 Followed by another single quote, returns to the position at
		 which the last "large" movement command was executed, or the
		 beginning of the file if no such movements have occurred.
		 All marks are lost when a new file is examined.

     /pattern	 Search forward in the file for the N-th line containing the
		 pattern.  N defaults to 1.  The pattern is a regular expres‐
		 sion, as recognized by ed.  The search starts at the second
		 line displayed.

     ?pattern	 Search backward in the file for the N-th line containing the
		 pattern.  The search starts at the line immediately before
		 the top line displayed.

     /!pattern	 Like /, but the search is for the N-th line which does NOT
		 contain the pattern.

     ?!pattern	 Like ?, but the search is for the N-th line which does NOT
		 contain the pattern.

     n		 Repeat previous search, for N-th line containing the last
		 pattern (or NOT containing the last pattern, if the previous
		 search was /! or ?!).

     E[filename]
		 Examine a new file.  If the filename is missing, the "cur‐
		 rent" file (see the N and P commands below) from the list of
		 files in the command line is re-examined.  If the filename is
		 a pound sign (#), the previously examined file is re-exam‐
		 ined.

     N or :n	 Examine the next file (from the list of files given in the
		 command line).	 If a number N is specified (not to be con‐
		 fused with the command N), the N-th next file is examined.

     P or :p	 Examine the previous file.  If a number N is specified, the
		 N-th previous file is examined.

     :t		 Go to supplied tag.

     v		 Invokes an editor to edit the current file being viewed.  The
		 editor is taken from the environment variable EDITOR, or
		 defaults to vi(1).

     = or ^G	 These options print out the number of the file currently
		 being displayed relative to the total number of files there
		 are to display, the current line number, the current byte
		 number and the total bytes to display, and what percentage of
		 the file has been displayed.  If more is reading from stdin,
		 or the file is shorter than a single screen, some of these
		 items may not be available.  Note, all of these items refer‐
		 ence the first byte of the last line displayed on the screen.

     q or :q or ZZ
		 Exits more.

ENVIRONMENT
     More utilizes the following environment variables, if they exist:

     MORE	 This variable may be set with favored options to more.

     EDITOR	 Specify default editor.

     SHELL	 Current shell in use (normally set by the shell at login
		 time).

     TERM	 Specifies terminal type, used by more to get the terminal
		 characteristics necessary to manipulate the screen.
