To pass a value as response to linux command using QT

[chillin]

Hi all,
I am designing an application using QT for an embedded device and I got stuck in an issue. I can able to pass the linux command using system() function. For a particular command I need to enter the password dynamically in the application window. Please help me to send the value for the previous executed command, dynamically using QT application.

Thanks in advance....

I am not sure what you mean, but if you need more control over the external command, have a look at QProcess instead of system()

I think what chillin means is something like:

su -c "fdisk -l"

su -c "fdisk -l"

To copy to clipboard, switch view to plain text mode 

A command like this will ask for a password ...

yes graciano you are correct.

I will explain the issue bit clearly.
I am developing an application in which I will run some commands using system() function, which may request password for commands with "sudo" and "ssh", in that case I need to pass the password as a string to response the command which will be waiting to get the password as input. I need help (with example code) to pass the password to the commands which are executed using the system() function.

Well, if you insist on using the system function, then you are out of luck.

Please let me know (with scratch code) if any other function other than system() performs the same task.

Thank you in advance.

I suggest reading the replies then.
Comment #2 might be a good start.

I'm using linux and there's a reason about asking for a password...I read about echoing:

echo -e "tadaaa" | sudo -S format all

but, I prefer the asking annoy
