getty - Sets the terminal type, modes, speed, and line discipline
getty [-h] [-t time] line speed_label terminal line_discipline
getty -c file
-h Hold the carrier during the initialization phase; do not hang up.
Set the time period to the specified number of seconds. Drop the line
after that amount of time if nothing is typed.
-c Check the specified gettydefs file.
The getty command sets and manages terminals by setting up speed, terminal
flags, and the line discipline. If command options are provided, getty
adapts the system to those specifications. getty prints the login prompt,
waits for the user to enter a username, and invokes the login command.
getty uses the /etc/gettydefs file for terminal information. The line
argument refers to the device name in /dev. The speed_label argument is a
pointer into the /etc/gettydefs file where the definitions for speed and
other associated options are located. The terminal argument specifies the
name of the terminal type. The line_discipline argument specifies the name
of the line discipline.
The second syntax for the getty command provides a check option. When
getty is invoked with the -c option and filename argument, it checks the
specified file in the same way it scans gettydefs for terminal information,
then prints the results to standard output.
By default, the getty daemon writes the login string specified in the mes-
sage field of the /etc/gettydefs file to any terminal spawned or respawned
from the /etc/inittab file. If an /etc/issue file is present, getty reads
the file and writes its contents to the terminal prior to writing the login
string specified in the /etc/gettydefs file.
Specifies the command path.
Specifies the terminal line database file.
Specifies the path name for the issue identification file.
