Here is how to log in on the linux command line.

By default, REDHAT Linux 9.0 automatically launches X-Window to enter the graphical interface when it starts. And many diehard Linux players are used to working in the Console character interface, or some players think that X-Window starts too slowly and prefer intuitive and fast Console operations.

1.linux command line login: enter the character interface

In order to go directly to the Console interface when logging in on the linux command line, we can edit the / etc/inittab file. Find the id:5:initdefault: line, change it to id:3:initdefault:, and restart the system. We can see that simply changing 5 to 3 can realize the transition to the X-Window graphical operating interface or Console character interface at startup. This is because the Linux operating system has six different operating levels (run level). Under different operating levels, the system has different states, which are:

0: stop (remember not to set initdefault to 0, as this will prevent Linux from starting)

1: single-user mode, just like the security mode under Win9X.

2: multi-user, but no NFS.

3: full multi-user mode, standard run level.

4: generally not, you can use it to do something in some special cases.

5:X11, that is, into the X-Window system.

6: restart (remember not to set initdefault to 6, as this will cause Linux to restart again and again).

Runlevel 3 is the standard Console character interface mode we want to enter.
