How to pass password to "su" as a parameter within a shell script?

[Binu Raj]

Hi All

I need to add an entry to the /etc/services file while running a shell script as a normal user. But I don't want su to prompt me for the root password instead it can be passed on to the shell script by a GUI interface(I can make this interface not to display the password). Or I can accept the password as an argument to the script.

The shell script can add desired entries to the services file and then exit.

Can somebody out there help me?

Thanks in advance

Regards

Hi

Try sudo

A method of using root commands is with the program called sudo. Information is available at:

www.courtesan.com/sudo/

Please note that Hewlett-Packard does not support sudo.

Otherwise implement a script with ssh, which is hp supported:

or


create a setuid executable, whose only function is to add/remove that service.

You can download a thirdparty tool called expect using this you can pass the password to su or password command.

Do somthing like that

Create a little script that belongs to root and group admin ( for example ). your user belongs to group admin, too. This little script will add your line to /etc/services.

Then set the s-Bit on that script.
#ll myscript.sh
-rw-r--r-- 1 root admin 123 Jul 24 10:55 myscript.sh

#chmod 550 myscript.sh
# chmod g+s myscript.sh
#ll myscript.sh
-r-xr-s--- 1 root admin 123 Jul 24 10:55 myscript.sh

And now you can use this script in your main script.
