NAME    [Toc]    [Back]

     ul -- do underlining

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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 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 appropriate
 dashes `-'; this is useful when you want to look at the
	     underlining which is present in an nroff output stream on a crtterminal.


     -t terminal
	     Overrides the terminal type specified in the environment with
	     terminal.

ENVIRONMENT    [Toc]    [Back]

     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)

BUGS    [Toc]    [Back]

     The nroff(1) command 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    [Toc]    [Back]
