Virtual Consoles


A virtual console is a command line where you can log into and control Linux. As RHEL is a multi terminal operating system, you can log into Linux, even with the same user ID, several times. It's easy to open a new virtual console. Just use the appropriate ALT-function key combination. For example, pressing ALT-F2 brings you to the second virtual console. You can switch between adjacent virtual consoles by pressing ALT-RIGHT ARROW or ALT-LEFT ARROW. For example, to move from virtual console 2 to virtual console 3, press ALT-RIGHT ARROW.

You can switch between virtual terminals by just press the ALT+CTRL+Funcation key combinations.
ALT + CTRL + F1  for terminal 1
ALT + CTRL + F2  for terminal 2
ALT + CTRL + F3  for terminal 3
ALT + CTRL + F4  for terminal 4
ALT + CTRL + F5  for terminal 5
ALT + CTRL + F6  for terminal 6
ALT + CTRL + F7  for terminal 7
Terminal 7 is by default graphic mode beside it all six terminal are CLI based. Open any terminial by press ALT+CTRL+F1 key combinations. root account is automatically created when we install Linux.
Type root on login name and press enter key, now give password ( no asterisk character like window to guess the password length) When you login from root account you will get # sign at command prompt , and when you login from normal user you will get $ prompt.
