NAME

ul

– do underlining

 

SYNOPSIS

ul

[-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
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 underline, 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

output stream on a crt-terminal.

-t terminal


Overrides the terminal type specified in the environment with
terminal


 

ENVIRONMENT

The following environment variable is used:


TERM


The
TERM

variable is used to relate a tty device
with its device capability description (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)).


 

SEE ALSO

man(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.

ul

command appeared in
