equivalent command of net group /domain for linux?

Question

I've been searching for quite a while for this, And couldn't find it anywhere.

Firstly, Is there equivalent command to:

wmic computersystem get domain

Which return the current user primary domain.

And I've been wondering whether there's an equivalent command of:

net group /domain

A command that returns all the global groups of user current domain.

So far I've been trying to search in different network files at /etc/, Currently the only relevant file I've found was reslov.conf which hold all the DNS, And it might contain more information than i actually need. [Which means that i'll have to query each domain there and 'ask' whether the user is associated with that domain] is there a way which is more efficient than that?

Thanks.

Un*x hostname

host.domain has address 192.168.1.35

See man host, man dig and man hostname. Have also a look at See also sections in man pages.

The concept of domain you mention is ambiguous.

The equivalent of wmic computersystem get domain is dnsdomainname .

This isn't the command to return the current user primary domain (Active Directory domain or otherwise).

That command for Active directory domain for a given Unix user mapped with samba is

wbinfo --sid-to-fullname `wbinfo --uid-to-sid username` | awk -F "\\" '{print $1}'. 

Also see the following related StackOverFlow question.

The equivalent of net group /domain is net ads group -w <domainname>, which is provided by Samba. The net group /domain isn't for a current user as you have described it, if you want the command equivalent of your description you will need to add -U <username> to the equivalent given.

If you are just looking for a command to get the groups of the current user, then getent group | grep username for the unix groups and existing Windows groups to Unix groups as per the Winbind configuration, or

wbinfo --user-domgroups `wbinfo --uid-to-sid username` 

for the global groups of a current user in a domain.
