On Linux, if we would like to restart our process when it is down without expect, we can achieve this goal by
1) As a service, can be used as 'service start/stop program' etc
Write a script which starts/stops the program and place them under /etc/init.d/ and create corresponding symbolic link under rc{1-5}.d to the script.
2) Configure the /etc/inittab which can restart the program if it dies
Example:
Append the following line to /etc/inittab and then issue 'telinit q' to tell init process to reload the changes.
lm:5:respawn:/usr/local/sbin/LSI_master
Reference:
man 8 init/inittab
