- Let's check out the commands
that we have seen in this lesson.
So useradd, which adds users and usermod,
which allows you to modify user properties.
Userdel allows you to delete users.
And likewise, we have groupadd,
groupmod and groupdel.
Then there is id.
Id shows you information about user accounts.
It is useful because you can see the groups
that the user is a member of.
And getent allows you to get information
out of an administrative database.
So even if your user comes from LDAP,
getent passwd username,
they'll show you properties of that user.
Passwd the good olds to change passwords.
And chage is more about changing password properties.
Now we have w, which is the shortest command
on Linux, actually.
It shows all the users currently logged in
and a little bit of details about these users.
Who is also showing you these users currently logged in,
but not as much details as w.
Vipw, which is the password editor
and vigr, which is the /etc/group editor.
And last we have seen loginctl,
which allows you to do session management.
