NAME

ul -- do underlining

SYNOPSIS

ul [-i] [-t terminal] [file ...]

DESCRIPTION

The ul utility 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 envi- ronment 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 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 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

The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the exe- cution of ul as described in environ(7).

EXIT STATUS

The ul utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

colcrt(1), man(1), nroff(1)

HISTORY

The ul command appeared in 3.0BSD.

BUGS

The nroff(1) command usually outputs a series of backspaces and under- lines intermixed with the text to indicate underlining. No attempt is made to optimize the backward motion. DragonFly 3.9 December 30, 2013 DragonFly 3.9
