Help with su
I was trying to use "su - <account>" but it prompts me for password in interactive mode. How do I write main.sh script that executes various commands by logging in as different accounts and login profiles. Is there a way to automatically redirect the password for "su" command to accept the password.

Please guide me further...

Thanks...

It is very difficult to redirect a password into su and this is intentional. Storing passwords and automatically logging into accounts is very dangerous and often a bad idea.

sudo can be configured to login without passwords, it is very flexible; but be careful to only give such permissions in a very limited and specific way.

Help with su
Hi,

I already tried using sudo but i don't have access to it,so that's why i am compelled to use it with su..

Is there no way out by which we can pass the password along with the username while using su....

What you could do is make "root" the owner of the file (and chmod 500), and then run your script. It won't prompt "root" for passwords.

Hi,

I can't make the roort owner of the file as I don't have rights to do so.

Is there no other alternative to do so???

I have heard about expect utility ,but it also works for root only.

Can anyone give any solution to the problem ?

thanks in advance...

Can anyone help me for the above??

I am unable to implement the logic of expect in my script.

Any help of whatsoever magnitude may prove very useful..

Thanks in advance...

Instead of using su or sudo, you could use ssh with key-based authentication. See my reply on a similar thread here:
