NAME
     ul	-- do underlining

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

DESCRIPTION
     The ul utility 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	envi-
     ronment variable TERM.  The file /etc/termcap 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 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 appropri-
	     ate dashes	`-'; this is useful when you want to look at the un-
	     derlining 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 termcap(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	environ(7)).

SEE ALSO
     colcrt(1),	man(1),	nroff(1)

BUGS
     The nroff(1) command usually outputs a series of backspaces and under-
     lines intermixed with the text to indicate	underlining.  No attempt is
     made to optimize the backward motion.

HISTORY
     The ul command appeared in	3.0BSD.
