sudo: I can't get it to run multiple commands. example within...

Good day all,

I need to get this to work, however I'm having difficulty with sudo. Take a look.

Code:

$ echo su_password | sudo -S { echo smb_password; echo smb_password; } | smbpasswd -s smb_user

It needs to be scripted, and sudo doesn't seem to understand the commands that follow it even though they work as root. Again keep in mind that the passwords need to be passed in like this because this needs to be scripted. If someone can get this to work I'll be their best friend for life...

echo su_password

The return from this will be: su_password.

If you want the value that is assigned to su_password, do this: echo $su_password.

If you want that value piped to sudo, do this: $(echo $su_password) | sudo, or the older but still valid `echo $su_password` | sudo (note the backticks around echo $su_password).

Sudo isn't having problems with the password. It's having problems with the commands that follow it. Assume that there are no variables in the sample code I posted (those are all literals).

Two ways I can think of to correct that:
a) add the commands which follow sudo into /etc/sudoers for the user who will be running the script.
example: # george can run these commands without a password
george ALL = NOPASSWD: /path/to/smb_password, /path/to/smb_password;

b) set up /etc/sudoers to allow the user to run all commands as root using the sudo command.
example: george ALL = (ALL) ALL
