How to run the shell script automatically when the kernel boots up

Because the root file system is mounted in Read-only mode, we need to re-mount it using writable

permission.

# mount -o remount,rw /dev/sda1/

Copy the example shell script fixtime to directory /etc/init.d, and then use chmod 755 fixtime to

change the shell script mode.

# chmod 755 fixtime

Next, use vi editor to edit the file /etc/inittab.

# vi /etc/inittab

Add the following line to the bottom of the file:

ntp : 2345 : respawn : /etc/init.d/fixtime

After you finish writing or modifying the code, remember to execute “umount /” to change the

root directory back to Read-only mode.

# umount /

Use the command #init q to re-initialize the kernel.

# init q
