|UL(1)||General Commands Manual||UL(1)|
ulutility 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 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,
uldegenerates to cat(1). If the terminal cannot underline, underlining is ignored. During the translation some other special characters also get translated. E.g. TAB gets expanded to spaces. The following options are available:
- Underlining is indicated 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.
- Overrides the terminal type specified in the environment with terminal.
TERMenvironment variables affect the execution of
ulas described in environ(7).
ulutility exits 0 on success, and >0 if an error occurs.

ulcommand appeared in 3.0BSD.
BUGS¶The nroff(1) command usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining. No attempt is made to optimize the backward motion.
