SYNOPSIS
ul
[-t
terminal]
[-i]
[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 type specified in the environment.
The
terminfo(4)
file corresponding to
TERM
is read to determine the appropriate sequences for underlining.
If the terminal is incapable of underlining,
but is capable of a standout mode, the standout mode is used instead.
If the terminal can overstrike,
or handles underlining automatically,
ul
degenerates to
cat.
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
present in an
nroff
output stream on a
CRT
terminal.
WARNINGS
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.
