The getty command sets and manages terminals by setting up speed, ter‐
minal 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
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 speci‐
fies the name of the terminal type. The line_discipline argument speci‐
fies 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
message 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.
