.SH NAME
ttytype \- terminal device to default terminal type mapping
.SH DESCRIPTION
The
.I /etc/ttytype
file associates
.BR termcap (5)
and
.BR terminfo (5)
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
.I /dev/
prefix).
.P
This association is used by the program
.BR tset (1)
to set the environment variable
.B TERM
to the default terminal name for
the user's current tty.
.P
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 UNIX systems.
.SH FILES

.I /etc/ttytype
