ul(1)ul(1)NAMEul - Translates underlining for display on a terminal
SYNOPSISul [-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.
OPTIONS
Causes the ul command to indicate underlining by a separate line con‐
taining 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 ter‐
minal 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.
DESCRIPTION
The ul command translates underscores to the sequence that indicates
display underlining for the terminal in use, as specified by the TERM
environment variable.
FILES
