using shell commands in my c program

using shell commands in my c program

I am programming under Ubuntu, using c. I would like to use shell commands, like "ls", and print the result in the stdout. Does anyone know how I can do? Thanks

RE: using shell commands in my c program

I found out that this code would work:


char cmd[100];
sprintf(cmd, "ls");

But I would like to be able to use also sudo commands without the shell stopping for the password request. Is there a way to  send the password as well together with the command?


RE: using shell commands in my c program

You could type "man sudo" and check for yourself.
The only thing I see that might work is the -S option.
I don't have Linux booted up now to try this myself, but try something like this:


sudo -S yourCmd < yourPassword
