[GTALUG] (question) What is the purpose of UID==GID?

[Alvin Starr]

GID does not have to equal UID.
It just does by convention.
If you can keep the relationship then it makes admin a slight bit easier.

For example if you do an ls  and get

   4 drwxrwxr-x.  2  108 108    4096 Feb 23  2015 foo.bar

you know the owner/group are set to a reasonable value as opposed to

   4 drwxr-xr-x.  7 1000 500    4096 Dec 14  2012  bar.baz

where you now need to lookup the GID for UID 1000.
