I am using Debian 8.
Executing id gives this output:
uid=1000(myUserName) gid=1000(myUserName) groups=1000(myUserName),48(sudo)
Is there anything special about a group that's automatically created when a user is created vs. a group that's created with groupadd?
Is the display of "gid=1000(myUserName)" redundant to the display of "groups=1000(myUserName),48(sudo)", or is the display of "gid=1000(myUserName)" meant to convey something to me that the display of "groups=1000(myUserName),48(sudo)" does not?
