agetty [options] port [baudrate...] [term_]

agetty opens a tty port, prompts for a login name, and invokes the /bin/login command. It is normally invoked by init(8). The command provides features useful for hardwired and dial-in connections, including automatic parity detection, baud rate deduction from modem messages, and optional hardware flow control.

-8, --8bits

Disable parity detection for 8-bit clean terminals

Automatic login without prompting for username

Enable RTS/CTS hardware flow control

Skip displaying /etc/issue

Don't clear screen before login prompt

Use alternative login executable

Control carrier detect requirement

Extract baud rate from modem status messages

Don't prompt for login name

Change the root directory

Write a specific fake host into the utmp file

Terminate if no input within timeout

/etc/issue

Pre-login message displayed before the login prompt. Supports escape codes for system information.

Operating system identification data used by agetty for \S escape in /etc/issue.

The baud rate is the speed of data transfer between a terminal and a device over a serial connection. Default is 9600 for serial terminals.

Part of util-linux package. Alternative to the traditional getty command with additional features for modern Linux systems.

login(1), init(8), getty(8)
