ul - do underlining
ul [-i] [-t terminal] [filename...]
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 appropri-
ate 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.
Override the terminal kind specified in the environ-
ment. If the terminal cannot underline, underlining is
ignored. If the terminal name is not found, no under-
lining 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.
ul returns exit code 1 if the file specified is not found.

nroff usually generates a series of backspaces and under-
lines intermixed with the text to indicate underlining. ul
makes attempt to optimize the backward motion.
