- Issue of the topic: By Mistake Run Command sudo usermod -G i2c openhab
Later i found need to run sudo usermod -a -G i2c openhab
I was having issue while accessing python script from user openhab
so I Ran Command from search results found on google and i am little nervous that i removed openhab from all other groups and added only to i2c.
Now how can i revert or undo changes ? what are the default groups to which openhab user belongs ?
