DDEESSCCRRIIPPTTIIOONN
MMoorree 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.) _F_i_l_e may be a single dash (``-''), implying stdin.
OOPPTTIIOONNSS
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.
--cc Normally, mmoorree will repaint the screen by scrolling from the
bottom of the screen. If the --cc option is set, when mmoorree needs
to change the entire display, it will paint from the top line
down.
--ee Normally, if displaying a single file, mmoorree exits as soon as it
reaches end-of-file. The --ee 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 mmoorree will exit at
end-of-file regardless.
--ii The --ii option causes searches to ignore case; that is, upper-
case and lowercase are considered identical.
--nn The --nn flag suppresses line numbers. The default (to use line
numbers) may cause mmoorree to run more slowly in some cases, espe-
cially with a very large input file. Suppressing line numbers
with the --nn flag will avoid this problem. Using line numbers
means: the line number will be displayed in the == command, and
the vv command will pass the current line number to the editor.
--ss The --ss option causes consecutive blank lines to be squeezed
into a single blank line.
--tt The --tt option, followed immediately by a tag, will edit the
file containing that tag. For more information, see the
ctags(1) command.
--uu By default, mmoorree treats backspaces and CR-LF sequences special-
ly. Backspaces which appear adjacent to an underscore charac-
ter 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 --uu option causes backspaces to always be
displayed as control characters, i.e. as the two character se-
quence ``^H'', and CR-LF to be left alone.
--xx The --xx option sets tab stops every _N positions. The default for
_N is 8.
--// The --// option specifies a string that will be searched for be-
fore each file is displayed.
CCOOMMMMAANNDDSS
Interactive commands for mmoorree are based on vi(1). Some commands may be
preceeded by a decimal number, called N in the descriptions below. In
the following descriptions, ^X means control-X.
hh help: display a summary of these commands. If you forget all
the other commands, remember this one.
SSPPAACCEE or ff or ^^FF
Scroll forward N lines, default one window. If N is more than
the screen size, only the final screenful is displayed.
bb or ^^BB 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.
jj or RREETTUURRNN
Scroll forward N lines, default 1. The entire N lines are
displayed, even if N is more than the screen size.
kk Scroll backward N lines, default 1. The entire N lines are
displayed, even if N is more than the screen size.
dd or ^^DD 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.
uu or ^^UU 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.
gg Go to line N in the file, default 1 (beginning of file).
GG Go to line N in the file, default the end of the file.
pp 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 mmoorree has already read to the end of the file. It is
always fast, but not always useful.)
rr or ^^LL Repaint the screen.
RR Repaint the screen, discarding any buffered input. Useful if
the file is changing while it is being viewed.
mm 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 postion 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.
//_p_a_t_t_e_r_n
Search forward in the file for the N-th line containing the
pattern. N defaults to 1. The pattern is a regular
expression, as recognized by ed. The search starts at the
second line displayed.
??_p_a_t_t_e_r_n
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.
//!!_p_a_t_t_e_r_n
Like /, but the search is for the N-th line which does NOT
contain the pattern.
??!!_p_a_t_t_e_r_n
Like ?, but the search is for the N-th line which does NOT
contain the pattern.
nn Repeat previous search, for N-th line containing the last pat-
tern (or NOT containing the last pattern, if the previous
search was /! or ?!).
EE [_f_i_l_e_n_a_m_e]
Examine a new file. If the filename is missing, the "current"
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-examined.
NN or ::nn Examine the next file (from the list of files given in the
command line). If a number N is specified (not to be confused
with the command N), the N-th next file is examined.
PP or ::pp Examine the previous file. If a number N is specified, the N-
th previous file is examined.
::tt Go to supplied tag.
vv Invokes an editor to edit the current file being viewed. The
editor is taken from the environment variable EDITOR, or de-
faults to vi(1).
== or ^^GG 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 mmoorree 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 reference the first byte
of the last line displayed on the screen.
qq or ::qq or ZZZZ
Exits mmoorree.
EENNVVIIRROONNMMEENNTT
MMoorree utilizes the following environment variables, if they exist:
MORE This variable may be set with favored options to mmoorree.
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.
