AGETTY Linux Command
What is Linux agetty Command?
Explanation
AGETTY Command:
The agetty command is the shortform of the "Alternative Linux Getty". This command opens a tty port, prompts for a login name and invokes the /bin/login command. It is normally invoked by init(8). Use agetty --help options to know various options that could be used with the "agetty" command.SYNTAX :
agetty [options] line baud_rate,... [termtype] agetty [options] baud_rate,... line [termtype]
ARGUEMENTS:
| port | A path name relative to the /dev directory. If a "-" is specified, agetty assumes that its standard input is already connected to a tty port and that a connection to a remote user has already been established. Under System V, a "-" port argument should be preceded by a "--". |
| baud_rate,... | A comma-separated list of one or more baud rates. Each time agetty receives a BREAK character it advances through the list, which is treated as if it were circular. Baud rates should be specified in descending order, so that the null character (Ctrl-@) can also be used for baud rate switching. |
| term | The value to be used for the TERM environment variable. This overrides whatever init(8) may have set, and is inherited by login and the shell. |
