UL(1)UL(1)NAMEul - do underlining
SYNOPSISul [ -i ] [ -t terminal ] [ name ... ]
DESCRIPTION
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 appropriate dashes `-'; this is useful when you want to look
at the underlining which is present in an nroff output stream on a crt-
terminal.
SEE ALSOman(1), nroff(1), colcrt(1)BUGS
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.
