su -m passwordless?

Allanm — Thu, 24 Mar 2011 21:04:31 GMT

Hi!

I have a script which prompts for password for a non-root user, can I avoid that?

su -m
Prompts for a password.

Its a startup script and the start up fails?

How can I fix this?

Thanks.

Hi:

Startup scripts are run as the 'root' user and thus you can launch *your* script from within the startup wrapper with:

su - someuser -c '/usr/local/bin/someuser.sh'

If a non-root process attempts to do a 'su' an interactive password prompt will be offered. You can't defeat this with redirection. In that case, your best recourse is probably to use 'expect':
