Setting the Run-Level

To set the Linux run-level and execution priority of a program, use the following command (because the root

file system is mounted in Read-only mode, we need to re-mount it with write permission).

Edit a shell script to execute /root/tcps2-release and save to tcps2 as an example.

#cd /etc/rc2.d

#ln –s /etc/root/tcps2 S60tcps2

#ln –s /etc/root/tcps2 k30tcps2

The command SxxRUNFILE has the following meaning:

S: Start the run file while Linux boots up.

xx: A number between 00-99. The smaller number has a higher priority.

RUNFILE: The script file name

The command KxxRUNFILE has the following meaning:

K: Start the run file while Linux shuts down or halts.

xx: A number between 00-99. The smaller number has a higher priority.

RUNFILE: The script file name

To remove the daemon, remove the run file from /etc/rc2.d by using the following command:

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

back to Read-only mode.
