c++ calling bash?
 

Hi all. I am pretty new to programming as a whole... in my first c++ class and have done a little playing around in bash. My question is this:

I have written a bash script to install a bunch of packages (automated linux from scratch). The code was relatively simple, but the problem I have is that you have to do a "chroot" and "login" a couple of times, which gives you a new bash prompt.... you're not in the program any more. I was wondering if I could write a c++ program which will call the bash scripts (one for each new login) and let me make the program run through w/ out the user needing to call another script.

Is there a way to do this? or would it be better to make it purely c++? if so, how would I use c++ to do system stuff (bash operations)?

I did read that other thread here, but I don't think that it's the same problem I have (if it is, I don't understand it).

Any help would be great. Thank you.

You can run every system command (with or without parameters) using system function. I don't know if it fits your needs, but you can read more about it when you run
man system.

Also check out the fork function (man fork) as it will allow you to spawn a process you don't have to wait for... And the exec functions are also sometimes helpful for executing things (man exec).

Do some housekeeping stuff within the bash skript. Modify your skript that it writes a message into a log file before executing a command, which will give you a new prompt. Then, change the file .bashrc to restart your skript, which should now parse the log file and jump to the part where it last time was exited.

I think this will be easier than using c++.

thanX Azrael sounds like a good idea
I'll try and see what I can up with.
