The command dscacheutil -q group will output all groups with their name, ID numbers, and list of members. Be warned, when I say it will output all the groups, I mean all the groups, including built-in system ones mortals were never meant to see. I'm just saying, don't freak out there are so many groups for a single-user system.
root as the superuser is in a ...
Alternative methods for listinggroupsand theirgid:
List sorted by group name:
dscl . list /Groups PrimaryGroupID
List sorted by group gid:
dscl . list /Groups PrimaryGroupID | tr -s ' ' | sort -n -t ' ' -k2,2
List groups with members:
dscl . list /Groups GroupMembership
Note: neither dscacheutil nor dscl list members of the group staff other than root....

There's only one reliable way to get all members of a group in OS X and the reply from 2DD8847 covers that. As for "why" I can't offer a logical explanation. All I can tell you is what differentiates the results.
These approaches fail to include users that are only members of the group via PrimaryGroupID. One way to think of it is that these users not ...
One way to change your group is through the MacOS System Preferences panel. Open it, and then open the Users & Groups panel. Unlock the lock icon in the bottom-left so that you can enter your password and make changes.
Once the panel is unlocked, you can right-click (or option-click) on the user you want to change and select Advanced Options from the ...
Staff is the default group that all users on OS X are in. You're simply seeing that 'staff' is the group that's set to have read permissions on your home directory (as it should be).
Although the group has read permissions on that directory, you'll notice that they do not have read permissions on most folders and files within. Here is some additional info ...
EDIT: The problem is now fixed in Homebrew:
If you still experience the problem, update Homebrew like this:
If you want to know what the problem was, I have kept my original answer below.

The reason that script doesn't delete all the bogus groups is that it only repeats 50 times, so it will only delete 50 in one go.
This script will delete every group with the name that you input (it asks you with a dialog box) until it can't find any more:
set counter to 0
display dialog "Name of group to delete?" default answer ""
set theGroupName to text ...
By default, new files inherit the group assigned to the directory they're created in. /tmp (actually /private/tmp) is assigned to the wheel group, therefore your new files created there get assigned to the wheel group.
BTW, if you're worried that this assignment is going to cause problems, don't. The default permissions on new files in macOS gives the group ...
Yes, you can do it, but it's a bit complicated. Permissions on macOS are rather complex; the Finder hides most of the complexity, but at the command line it's fully exposed and you have to deal with it.
Really short answer: use chmod +a to add access control entries, ls -le to view them, and man chmod and man ls for details.
Medium-length answer: to add (...
What exactly do you want to achieve/do?
This command lists all users in the staff group:
dscl . -list /Users PrimaryGroupID | grep ' 20$'
Explanation: The staff group has the PrimaryGroupID of 20.
Here is a script written quickly. Should work. But I have not revised it down to be efficient.
tell application "Contacts"
(*get the names of all groups *)
set theGroupNames to name of groups
(*choose you current group, the one to keep entries*)
set text_returnedCurrent to choose from list theGroupNames with prompt "Choose Current Group" ...
Go to "groups" in "Contacts" and uncheck all the groups except the one the contact you want to move is in.
Search for the contact you want to move and "Share" the contact to your own email address or phone # via text.
Click "edit" on the contact you just sent and delete it.
Go back to Groups and uncheck the group the contact was sent from.
Leave only the ...
To list all the groups to which a user belongs, type:
[username] argument is optional. By default, the logged in user is assumed. The output will include the numeric user id uid, and the list of all the groups along with their group id gid, of which the user is member of. The first group in the output is the user's primary group.
To list ...
Use the find command (and save the output listing. This may take a while)
find / -group messagebus -print
to ensure that ownership for files can be corrected later with a chgrp command.
The following be used
dscl . -change /Groups/messagebus PrimaryGroupID 20 10000
(1) Yes and (2) yes (but can be no depending on configuration).
If all the recipients are on iMessage, then it will be an entirely group thing. Everyone sees everyone, and everyone gets all replies.
If you have Group Messaging disabled under Settings.app > Messages > Group Messaging, then they will send as individual text - replies will be separate. ...
From what I have seen the minute a non iMessage user is added to a bulk message it sends all the messages via SMS. I suspect however this is dependant on the carrier more then apple.
From testing, the verification of whether a user has iMessage enabled is done before the message is actually sent.
My best advice is for you to try it out and see. I don't ...
Found the answer that works from in a 4 year old post on this board.
This creates the user, and the group, with the specific gid.
dscl . -create /Users/vmail UniqueID 5000 PrimaryGroupID 5000 RealName "vmail"
It can be checked, because it runs silently, with the following. The command in my case gives the following output.
bash-3.2# dscl . -read /Users/...
This doesn't work on Chrome for Mac, so it may be the same on Windows & require that you use a different browser to achieve it...
Go to https://www.icloud.com/#contacts
In the left column, select your required group
Gear menu, bottom left -
Select All, then
The exported file contains all the contact details for that group of contacts.
For your purposes, it's best not to add yourself to an existing group.
To discover what groups are on your computer you will find most listed in /etc/group - less /etc/group will give it to you. You can create a new group by adding it to this list. man group will explain the format of this file. I usually create a group with an id from 600 to 699. Apple ...
