Virtual terminals in Linux

Linux virtual terminal-general Linux technology-Linux technology and application information. For more information, see the following section. The so-called virtual terminal is physically a software console on the local machine, rather than a real remote physical terminal. However, the virtual terminal is more unified in implementation, this is like Linux, which treats devices and general files equally.

Linux is a multi-terminal operating system. You can even use the same user ID to log on to multiple terminals at the same time.

By default, there are 6 console virtual terminals and 1 GUI terminal. To log on to the terminal in Red Hat Linux in the past, you can log on to the console virtual terminal through Alt + F1 to F6, and log on to the GUI terminal through Alt + F7. In Fedora Core 6 and Fedora7, you need to use Ctrl + Alt + Fn. You can also use Alt + left and right arrows on the console terminal to select a nearby Terminal (however, this key combination does not work in the GUI ).

Check/etc/inittab again

Linux is a very personalized system, which can be customized by yourself in many places. We have read the inittab file in the previous article. Now we need to read it again, in fact, we can also use this file to control the number of virtual terminals on Linux.

Here:

1: 2345: respawn:/sbin/mingetty tty1

2: 2345: respawn:/sbin/mingetty tty2

3: 2345: respawn:/sbin/mingetty tty3

4: 2345: respawn:/sbin/mingetty tty4

5: 2345: respawn:/sbin/mingetty tty5

6: 2345: respawn:/sbin/mingetty tty6

From 1 to 6, you have 6 console terminals. You can simply modify this part of the file and add or delete some console virtual terminals. For example, comment out the sixth line (Add "#" before it), or delete it to remove tty6, you can also add your seventh terminal by adding the following:

7: 2345: respawn:/sbin/mingetty tty7

You can simply modify the first and last numbers.
