I am a newbie python programmer and a linux learner.
I am working on a project that is an initial configuration tool for new users of linux as me. I want my program to reboot the computer after performing some task and then the same program should be started up from on the next reboot.

What shell programming is to be done ?
Hoping to get an early reply.
Thank you.

Firstly: there should be little need to reboot in the middle of an install. Linux, like all U*ix'ses, only should be rebooted if the kernel is updated or new non-plug&play hardware was installed

Having said that, some cases do exist and you probably want to look at /usr/bin/firstboot as an example... it could be you don't have it, unsure if it is a Redhat-only program. You might have to Google for it.

Also study how /etc/init.d and /etc/rc0.d through /etc/rc6.d work.

Finally, have a look at /etc/inittab and /etc/rc.sysinit.

Happy coding,
Walter.
