ul - do underlining
ul [ -i ] [ -t terminal ] [ name ... ]
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 -t option overrides the terminal kind
specified in the environment. 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 -i option causes ul to indicate underlining onto by a separate line containing appro-
priate dashes `-'; this is useful when you want to look at the underlining which is
present in an nroff output stream on a crt-terminal.

Nroff usually outputs a series of backspaces and underlines intermixed with the text to
indicate underlining. No attempt is made to optimize the backward motion.
