NAME

       ul - do underlining

SYNOPSIS

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

DESCRIPTION

       ul  reads  the  named  filenames  (or the 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. ul uses the /usr/share/lib/terminfo entry 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  can-
       not underline, underlining is ignored.

OPTIONS

       -t terminal     Override  the  terminal kind specified in the environment. If the terminal cannot underline, underlining is ignored. If the
		       terminal name is not found, no underlining is attempted.

       -i	       Indicate underlining by a separate line containing appropriate dashes `-'; this is useful when you  want  to  look  at  the
		       underlining which is present in an nroff(1) output stream on a CRT-terminal.

RETURN VALUES

       ul returns exit code 1 if the file specified is not found.

FILES

BUGS

       nroff  usually  generates a series of backspaces and underlines intermixed with the text to indicate underlining. ul makes attempt to opti-
       mize the backward motion.
