Linux interface/command line

$ Gedit/etc/inittab
Change 5 in ID: 5: initdefault to 3.

0: Shutdown (remember not to set initdefault to 0, because this will make Linux unable to start)
1: single-user mode, just like the security mode in Win9x.
2: multiple users, but not NFS.
3: full multi-user mode, standard operation level.
4: It is generally not used. In some special cases, you can use it to do something.
5: X11, which means entering the X-window system.
6: restart (remember not to set initdefault to 6, because this will make Linux continuously restart ).

Among them, running level 3 is the standard console character interface mode we want to enter.
