NAME
     ul	-- do underlining

SYNOPSIS
     ul	[-i] [-t terminal] [name ...]

DESCRIPTION
     Ul	reads the named	files (or standard input if none are given) and	trans-
     lates occurrences of underscores to the sequence which indicates under-
     lining for	the terminal in	use, as	specified by the environment variable
     TERM.  The	terminfo database is read to determine the appropriate
     sequences for underlining.	 If the	terminal is incapable of underlining,
     but is capable of a standout mode then that is used instead.  If the ter-
     minal can overstrike, or handles underlining automatically, ul degener-
     ates 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 appropri-
	     ate dashes	`-'; this is useful when you want to look at the
	     underlining 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.
