Please help me understand what the following means:
[Michael@michaels ~]$ grep Michael /etc/passwd
Below is my understanding:
- My username
- My shadowed password
- My userid
- A group id created just for me? When is this number different than my userid?
- Why is nothing shown between the two colons? What belongs here?
- My home directory
- My shell
[root@michaels Michael]# grep Michael /etc/group
- My group name
- What is the x for?
- My group id
- Any other usernames (surprisingly to me, not user ids) separated by commas.
