Linux How to assign directory to user group A week ago, I created a directory by terminal as user root. Today I logged in as normal user and opened this directory but it said that I dont have permission. Here is the way to grant permissions for user to read and write on this directory. Data in this example: - Directory name " Programming "; - New user group name " newGroup " - Current login user name " approved " Step 1: Login as root su Step 2: Create new user group groupadd newGroup Step 3: Add current user to newGroup usermod -a -G newGroup approved Step 4: List all users of newGroup and make sure it contains approved grep Programming /etc/group Step 5: Make newGroup as a owner of Programming chown -hR root:newGroup Programming Step 6: Grant permission for this group chmod -R 777 Programming Thats it ^_^ Source: https://askubuntu.com/questions/487527/give-specific-user-permission-to-write-to-a-folder-using-w-notation https://www.cyberciti.biz/faq/how...
