#All the script does is create the new specified group, cuts out all the names from /etc/group #and replaces all commas with a single space. It then places each name into it's own element #inside of an array called 'users'. It then goes through each element of the users array and #adds it to the group. To execute the command, type: ./nameofscript groupname
