Copy the above command-line to the Terminal, and then type members mygroup where mygroup is the name of an existing group.

There are five different ways that I know of that a user can be member of a group in OS X. The command dscl. So rather than trying to keep track of all those, it seems like a better idea to simply check the membership of every user on the system using dsmemberutil , and that's what the shell function and the script below do. This members script is equivalent to the shell function, but has nicer handling of invalid input:.

Similar to duperuser's answer, the following will print out only the users of the group admin with spaces in between:. The dscacheutil command is used to query information about various categories of the system's Directory Service cache. The -q option lets you specify the category you want to query.
