automated shell process?

[kraigory]

Alright- what I need is to automate a process that will replace one file on my hard drive with a file on a cd, and then reboot. I'm going to put this process on a custom linux live cd and have it autorun on startup. Then I will use it to update the file on multiple computers.

Sooo, how can I write a shell program that will take a file from x location and place it at y location, automatically overwriting any files already there, and then reboot the system? Maybe even eject the drive, THEN reboot. That'd be sweet.

Any help would be greatly appreciated! Thanks!

Well, let's see...

The mv command takes two arguments: the location of a file and the new location. It moves the file. Simple enough. Coincidentally, it also takes the -f option, which overwrites a file without asking for confirmation.

For rebooting, assuming that this is being run by a privileged user (and init scripts do count), there is the conveniently named reboot command. You can alternatively call shutdown -r now.

Finally, there is the (again aptly named) eject command that takes a device and ejects it.

alright thanks- i figured the commands were the same as in the terminal.

i guess my main question is, how exactly do you make such a program? Can you just write it in a text editor and save it as a certain file type, similar to how you would make a BATCH file in windows?
