NAME
ul - do underlining SYNOPSIS
ul [-i] [-t terminal] [filename]... DESCRIPTION
ul reads the named filenames (or the 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. ul uses the /usr/share/lib/terminfo entry 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 can- not underline, underlining is ignored. OPTIONS
-t terminal Override the terminal kind specified in the environment. If the terminal cannot underline, underlining is ignored. If the terminal name is not found, no underlining is attempted. -i Indicate underlining by a separate line containing appropriate 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. RETURN VALUES
ul returns exit code 1 if the file specified is not found. FILES
/usr/share/lib/terminfo/* ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWdoc | +-----------------------------+-----------------------------+ SEE ALSO
cat(1), man(1), nroff(1), attributes(5) BUGS
nroff usually generates a series of backspaces and underlines intermixed with the text to indicate underlining. ul makes attempt to opti- mize the backward motion. SunOS 5.11 17 Mar 1994 ul(1)
