ul - Translates underlining for display on a terminal
ul [-i] [-t terminal] [file...]
The ul command displays the named files (or standard input
if none are given) with underlining shown as it would be
on the printed page.
Causes the ul command to indicate underlining by a separate
line containing appropriate - (dashes). This is useful
when you want to look at the underlining in formatted
text output on a cathode ray tube (CRT) terminal. Overrides
the terminal kind specified in the environment. The
terminfo database 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
mode is used instead. If the terminal can overstrike, or
handles underlining automatically, ul acts like the cat
command, simply displaying data to the screen. If the
terminal cannot underline, underlining is ignored.
The ul command translates underscores to the sequence that
indicates display underlining for the terminal in use, as
specified by the TERM environment variable.
