ul
UL(1) BSD General Commands Manual UL(1)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 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 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 underlin-
ing 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 execution 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 underlines intermixed with the text to indicate underlining. No attempt is
made to optimize the backward motion.
