10 __DESCRIPTION__
11
12
13 Ul reads the named files (or standard input if none are
14 given) and translates occurrences of underscores to the
15 sequence which indicates underlining for the terminal in
16 use, as specified by the environment variable TERM.
17 The file /etc/termcap is read to determine the
18 appropriate sequences for underlining. If the terminal is
19 incapable of underlining, but is capable of a standout mode
20 then that is used instead. If the terminal can overstrike,
21 or handles underlining automatically, ul degenerates to
22 cat(1). If the terminal cannot underline,
23 underlining is ignored.

26 The following options are available:
27 -i Underlining is indicated by a separate line contain-ing appropriate dashes `-'; this is useful when youwant to look at the underlining which is present inan nroff
28 output stream on a crt-terminal.

42 The TERM variable is used to relate a tty device
43 with its device capability description (see
44 termcap(5)). TERM is set at login time,
45 either by the default termi- nal type specified in
46 /etc/ttys or as set during the login process by the
47 user in their login file (see
48 environ(7)).

59 The nroff(1) command usually outputs a series of
60 backspaces and underlines intermixed with the text to
61 indicate under- lining. No attempt is made to optimize the
62 backward motion.
