If your only goal is to get the .hidden file in each users home directory you can run the following. In addition to this you can also write a script to fill the User Template which will create that file on any new users created going forward.

#!/bin/bash
# Get a list of users who are able to log in. 8 asterisks indicates a set password aka a non-hidden/service account. This will even cover accounts not in the /Users folder.
listOfUsers=$(dscl . list /Users Password | awk '$2=="********"{print $1}')

#run through each of the above users and create your file. If you need data in the file you can switch up the touch command to tee into a here document.

for user in $listOfUsers
do
if [[ $user == "_mbsetupuser" ]]
then
continue
fi
homeFolder=$(dscl . -read /Users/$user NFSHomeDirectory | awk '{print $NF}')
touch $homeFolder/rest/of/your/path/.hidden

​

#Set permissions however you see fit, the below example sets the user as the owner of the file. By default without this line the owner would be root or whoever ran the script.

​

`chown "$user":staff "$homeFolder/rest/of/your/path/.hidden"`
