After reading around and talking to a friend who's done some bash scripting. I think I'm going to have to write a 'for' loop to define the variables after creating the group.

If/when I get this figured out I'll come back and share.

Well, here's what I've got. Probably way off but what do you think? Where have I gone wrong the most?

Code:

#!/bin/bash
#this is my attempt at writing a bash script which creates a non-admin group called 'cats'
#the script should add all users except the DOG and Shared users to the script
#this is my first attempt at writing a bash script and likely has errors
#don't run this script unless you know how to fix it first as it will likely cause your Mac to do odd things



# Change to the directory you want to use to parse though
cd /Users/

# Create a non-admin group using dseditgroup. Staff? what else would indicate it's to be a non-admin group?
# a group ID could be specified for more control

dseditgroup -o create cats -t staff
# not sure if this should have a -n included to indicate the node instead of using the default directory.

# This will loop though the directory specificed above and set each file and folder to variable a
for a in *;do
    # Looks to see if $a is a directory, if it is, then it continues, else it goes to done
    if [[ -d $a ]]; then
        # Excludes the Shared directory
        if [[ $a != "Shared" ]]; then
            # Excludes the dog directory
            if [[ $a != "dog" ]]; then
                # Excludes the DOG directory
                if [[ $a != "DOG" ]]; then
                    
                    dscl -u $a . -append /Groups/cats GroupMembership
                    # this is using dscl instead of dseditgroup to add all users indicated by the $a variable (excluding DOG and Shared above)
                    echo $a
                fi
            fi
        fi
    fi
done


dseditgroup -o checkmember . cats
#attempting to check the membership of the new group and have it print to verify it worked

echo $checkmember


exit

thanks for your feedback.

       being used to supplement the local /etc/group file with additional entries, groupdel cannot change  information  supplied  by  the  network
       nameservice.
