I was thinking to use gksudo. Is there anyway to see if these commands were successfully accomplished?
E.g.
gksudo -i > alex
And then if password confirmation will be successful, "1" or "successful" will be writen to file "alex"
Is this or something similar possible?
A few things...
1) You haven't given sudo anything to do, so I don't think that will work. If you want to change the password, why not sudo -u username passwd username? That will request the user's login and, only if successful, prompt him to change the password.
2) I don't think you really want to capture the output here, do you? You want the user to see it and interact with it. Using gksudo instead of sudo in a terminal means you don't get all this nice prewritten tested-to-death software to use(no google hits for gkpasswd). Why not use it?
3) Check the program's return status, not it's output. If you're unsure what an exit status is, try this from shell:
And the following program should do this:
Traditionally programs return 0 on success, nonzero on failure. Just check if it returned zero and you'll know if it succeeded.

I am thinking of using the system function at stdlib.h calling gksudo. Then writing a value to a file or something and then, through C++ check this value and decide if the access is accepted or not...
did a big mistake, changing root entry of /etc/passwd to
root:x:0:0:root:/root:/usr/bin/tmux split-window -v \; attach
as expected, now I can't login as root anymore. sudo ed /etc/passwd etc. doesn't work.
Any idea?
