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 file /usr/share/misc/terminfo 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 following environment variable is used:

     TERM  The TERM variable is used to relate a tty device with its device capability description (see termcap(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 for
	   example csh(1)'s setenv).

HISTORY

     The ul command appeared in 3.0BSD.

BUGS

     nroff(1) usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining.  No attempt is made to opti-
     mize the backward motion.

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/*
