TTYS(5)

NAME
ttys - terminal initialization data

SYNOPSIS
/etc/ttys

DESCRIPTION
The /etc/ttys file is read by the init program and specifies which terminal special files are to have a process created so that people can log in. There is one line in the /etc/ttys file for each terminal line.

The first character of a line in the /etc/ttys file is either `0' or '1'. If the first character on the line is a `0', init ignores that line. If the first character on the line is a `1', init creates a login process for that line.

The second character of a line in the /etc/ttys file is passed to getty(8). Getty uses this character to select an entry from the /etc/gettytab file (see gettytab(5)). The entries in /etc/gettytab describe characteristics, including baud rate, of various terminal classes. For normal lines, the second character is `0', although other characters can be used (as for example, with hard-wired terminals where speed recognition is unnecessary or which have special characteristics).

The remainder of a line in the /etc/ttys file is the terminal's entry in the device directory, /dev.

Note that editing /etc/ttys while the system is up and running in multiuser mode is not recommended.
