UL(1) BSD Reference Manual UL(1)NAMEul - do underlining
SYNOPSISul [-i] [-t terminal] [name ...]
DESCRIPTIONul 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 ter-
minal can overstrike, or handles underlining automatically, ul degen-
erates to cat(1). If the terminal cannot underline, underlining is ig-
nored.
The options are as follows:
-i Underlining is indicated by a separate line containing appropri-
ate 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.
-t terminal
Overrides the terminal type specified in the environment with
terminal.
ENVIRONMENT
TERM Used to relate a tty device with its device capability description
(see termcap(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 environ(7)).
SEE ALSOcolcrt(1), man(1), nroff(1)HISTORY
The ul command appeared in 3.0BSD.
BUGSnroff(1) usually outputs a series of backspaces and underlines intermixed
with the text to indicate underlining. No attempt is made to optimize the
backward motion.
