UL(1) BSD General Commands Manual UL(1) NAME ul -- do underlining SYNOPSIS ul [-i] [-t terminal] [name ...] 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 un- derlining 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). DIAGNOSTICS The ul utility exits 0 on success, and >0 if an error occurs. SEE ALSO colcrt(1), man(1), nroff(1) 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. HISTORY The ul command appeared in 3.0BSD. BSD August 4, 2004 BSD
