     ul - do underlining

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

     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 ncurses(3) library is used 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

     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-

     -t terminal

     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)).

     colcrt(1), man(1), nroff(1)

     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.

     The ul command appeared in 3.0BSD.
