ul -- do underlining
ul [-i] [-t terminal] [name ...]
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 speci-
fied by the environment variable TERM. 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 is used instead. If the terminal can overstrike, or
handles underlining automatically, ul degenerates to cat(1). If the terminal cannot under-
line, underlining is ignored.
The following options are available:
-i 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 out-
put stream on a crt-terminal.
Overrides the terminal type specified in the environment with terminal.
The following environment variable is used:
TERM The TERM variable is used to relate a tty device with its device capability descrip-
tion (see terminfo(5)). TERM is set at login time, either by the default terminal
type specified in /etc/ttys or as set during the login process by the user in their
login file (see setenv(1)).
man(1), nroff(1), colcrt(1)
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.
The ul command appeared in 3.0BSD.
