Linux permissions - user vs group permission

Question

I know that the permissions listing are for user , then the group and the third one is for other users.

my example :

_rwxr--r-- tooth face file1.txt
_rwxr--r-- eye face file2.txt
_rwxr--r-- leg face file3.txt

groups included

tooth : face head 
eye : face head 
leg : body

Now, my question is : whether "leg" will have rwx permissions to file3 as it is not a member in group "face" ?

Answer 1

The file permissions are:

_rwxr--r-- leg face file3.txt
 ^^^   ^^^
  |  ^^^ |
  |   |   others
  |   group
  owner

This means that:

• user leg has rwx permissions.
• other users from group face have r-- permissions.
• the rest of the users who are not in the group face have r-- permissions.

Since the owner is leg, this user will of course have rwx permissions.
