UL(1) BSD General Commands Manual UL(1)NAME
ul -- do underlining
SYNOPSIS
ul [-i] [-t terminal] [name ...]
DESCRIPTION
Ul reads the named files (or standard input if none are given) and translates occurrences of underscores to the sequence which indicates
underlining for the terminal in use, as specified by the environment variable TERM. The terminfo database is read to determine the appropri-
ate sequences for underlining. If the terminal is incapable of underlining, but is capable of a standout mode then that is used instead. If
the terminal can overstrike, or handles underlining automatically, ul degenerates to cat(1). If the terminal cannot underline, underlining
is ignored.
The following options are available:
-i Underlining is indicated by a separate line containing appropriate dashes `-'; this is useful when you want to look at the underlin-
ing which is present in an nroff output stream on a crt-terminal.
-t terminal
Overrides the terminal type specified in the environment with terminal.
ENVIRONMENT
The following environment variable is used:
TERM The TERM variable is used to relate a tty device with its device capability description (see terminfo(5)). TERM is set at login time,
either by the default terminal type specified in /etc/ttys or as set during the login process by the user in their login file (see
setenv(1)).
SEE ALSO man(1), nroff(1), colcrt(1)BUGS
Nroff usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining. No attempt is made to optimize
the backward motion.
HISTORY
The ul command appeared in 3.0BSD.
AVAILABILITY
The ul command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.

MORE(1) User Commands MORE(1)NAME
more -- file perusal filter for crt viewing
SYNOPSIS
more [-dlfpcsu] [-num] [+/pattern] [+linenum] [file ...]
DESCRIPTION
more is a filter for paging through text one screenful at a time. This version is especially primitive. Users should realize that less(1)
provides more(1) emulation plus extensive enhancements.
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.
-num This option specifies an integer which is the screen size (in lines).
-d more will prompt the user with the message "[Press space to continue, 'q' to quit.]" and will display "[Press 'h' for instructions.]"
instead of ringing the bell when an illegal key is pressed.
-l more usually treats ^L (form feed) as a special character, and will pause after any line that contains a form feed. The -l option will
prevent this behavior.
-f Causes more to count logical, rather than screen lines (i.e., long lines are not folded).
-p Do not scroll. Instead, clear the whole screen and then display the text.
Notice that this option is switched on automatically if the executable is named page.
-c Do not scroll. Instead, paint each screen from the top, clearing the remainder of each line as it is displayed.
-s Squeeze multiple blank lines into one.
-u Suppress underlining.
+/ The +/ option specifies a string that will be searched for before each file is displayed.
+num Start at line number num.
COMMANDS
Interactive commands for more are based on vi(1). Some commands may be preceded by a decimal number, called k in the descriptions below. In
the following descriptions, ^X means control-X.
h or ? Help: display a summary of these commands. If you forget all the other commands, remember this one.
SPACE Display next k lines of text. Defaults to current screen size.
z Display next k lines of text. Defaults to current screen size. Argument becomes new default.
RETURN Display next k lines of text. Defaults to 1. Argument becomes new default.
d or ^D Scroll k lines. Default is current scroll size, initially 11. Argument becomes new default.
q or Q or INTERRUPT
Exit.
s Skip forward k lines of text. Defaults to 1.
f Skip forward k screenfuls of text. Defaults to 1.
b or ^B Skip backwards k screenfuls of text. Defaults to 1. Only works with files, not pipes.
' Go to place where previous search started.
= Display current line number.
/pattern Search for kth occurrence of regular expression. Defaults to 1.
n Search for kth occurrence of last r.e. Defaults to 1.
!<cmd> or :!<cmd>
Execute <cmd> in a subshell
v Start up an editor at current line. The editor is taken from the environment variable VISUAL if defined, or EDITOR if VISUAL is
not defined, or defaults to "vi" if neither VISUAL nor EDITOR is defined.
^L Redraw screen
:n Go to kth next file. Defaults to 1.
:p Go to kth previous file. Defaults to 1.
:f Display current file name and line number
. Repeat previous command
ENVIRONMENT
More utilizes the following environment variables, if they exist:
MORE This variable may be set with favored options to more.
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.

HISTORY
The more command appeared in 3.0BSD. This man page documents more version 5.19 (Berkeley 6/29/88), which is currently in use in the Linux
community. Documentation was produced using several other versions of the man page, and extensive inspection of the source code.
