ttytype
TTYTYPE(5) Linux Programmer's Manual TTYTYPE(5)
NAME
ttytype - terminal device to default terminal type mapping
DESCRIPTION
The /etc/ttytype file associates termcap(5)/terminfo(5) terminal type names with tty lines. Each line consists of a terminal type, fol-
lowed 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 UNIX systems.
FILES
/etc/ttytype
the tty definitions file.
EXAMPLE
A typical /etc/ttytype is:
con80x25 tty1
vt320 ttys0
SEE ALSO
termcap(5), terminfo(5), agetty(8), mingetty(8)
