NAME

     ul -- do underlining

SYNOPSIS

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

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 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 underlin-
	     ing which is present in an nroff(1) output stream on a crt-terminal.

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

ENVIRONMENT

     The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the execution of ul as described in environ(7).

EXIT STATUS

     The ul utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

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

HISTORY

     The ul command appeared in 3.0BSD.

BUGS

     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.
