agetty Command Examples
Alternative
getty
: Open atty
port, prompt for a login name, and invoke the/bin/login
command. It is normally invoked byinit
. Note: the baud rate is the speed of data transfer between a terminal and a device over a serial connection. More information: https://manned.org/agetty.
- Connect
stdin
to a port (relative to/dev
) and optionally specify a baud rate (defaults to 9600):
agetty {{tty}} {{115200}}
- Assume
stdin
is already connected to atty
and set a timeout for the login:
agetty {{[-t|--timeout]}} {{timeout_in_seconds}} -
- Assume the
tty
is [8]-bit, overriding theTERM
environment variable set byinit
:
agetty -8 - {{term_var}}
- Skip the login (no login) and invoke, as root, another login program instead of
/bin/login
:
agetty {{[-n|--skip-login]}} {{[-l|--login-program]}} {{login_program}} {{tty}}
- Do not display the pre-login (issue) file (
/etc/issue
by default) before writing the login prompt:
agetty {{[-i|--noissue]}} -
- Change the root directory and write a specific fake host into the
utmp
file:
agetty {{[-r|--chroot]}} {{/path/to/root_directory}} {{[-H|--host]}} {{fake_host}} -
