login as root but run script as guest

[francois]

I am working in root mode. I would like to create a script to start chromium as user guest, from one command line if possible without having to issue the password for guest. Is this possible?

[brokenman]

Code: Select all

su - guest -c chromium

[aus9]

su - guest -c chromium

I am not sure if that will work but in a test of mtpaint I changed to root and then ran

Code: Select all

su -c guest mtpaint 
su: user mtpaint does not exist

but this does work

Code: Select all

su -c mtpaint guest

so as I don't have chromium installed I would suggest

Code: Select all

su -c chromium guest

aus9, you have the winning combination.

Thanks to both of you.

Sorry mixed the order. The correct aproach would be:

Code: Select all

su guest - -c mtpaint

su guest -
Starts a login shell for guest with guest environment.

-c command
Runs a command for su
