NAME

       ttytype - terminal device to default terminal type mapping

DESCRIPTION

       The  /etc/ttytype  file associates termcap/terminfo terminal type names with tty lines.	Each line consists of a terminal type, followed by
       whitespace, followed by a tty name (a device name without the /dev/) prefix.

       This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for  the  user's  current
       tty.

       This  facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a Unix minicomputer.
       It is little used on modern workstation and personal Unixes.

EXAMPLE

       A typical /etc/ttytype is:

	      con80x25 tty1
	      vt320 ttys0

FILES

       /etc/ttytype
	      the tty definitions file.

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 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 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
	   environ(7)).

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.

HISTORY

     The ul command appeared in 3.0BSD.
