Run Level

Run Level:

To check the run level we need to see the file /etc/inittab

#vi /etc/inittab

defaults run – level used by RHS are

0 : hault ( do not set init default to this)

1 : single user mode

2 : multi user mode without networking

3 : multi-user mode with networking

4 : unused

5 : X11 (Graphical)

6 : reboot

#runlevel : this command shows that in which run level you are at present

in init 3 runlevel, if you type command startx to go to the graphical mode then it will not ask you for password.

By default we have 6 virtual console (text mode), but we van increase or decrease the number of text mode simply by editing the file /etc/inittab

#vi /etc/inittab

line No 18 : id:5:initdefault

(we can change this value from 1 to 5 as per our need)

Line No 44 :

1:2345:respawn:/sbin/mingetty tty1

2:2345:respawn:/sbin/mingetty tty2

.

.

.

6:2345:respawn:/sbin/mingetty tty6

in these line if we add one more line the number of virtual console increase and if we remove one line , virtual console terminal decrease.

For adding

7:2345:respawn:/sbin/mingetty tty7

after editing this file we need to sane and exit

#init q : this command is used to activate the change made.

Welcome Message at the time of login:

#vi /etc/motd
