Any time I have used a script to create folders within the users' home directory, I have always followed up by adding a chown command to change the ownership of the folder(s) to the current user. Here's one I put together a few years ago that has worked consistently.

!/bin/sh

currentuser=/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }'
echo $currentuser

mkdir $HOME/Documents/PDFs for Client Reports
mkdir $HOME/Documents/PDFs for ATBs;
mkdir $HOME/Documents/PDFs for Estimates;
mkdir $HOME/Documents/PDFs for Insertion Orders

chown $currentuser $HOME/Documents/PDFs for Client Reports
chown $currentuser $HOME/Documents/PDFs for ATBs
chown $currentuser $HOME/Documents/PDFs for Estimates
chown $currentuser $HOME/Documents/PDFs for Insertion Orders

The script will first check if a directory is there if not make it, then if the file exists append it if not make the file and input information. The issue is that if the folder or file does not exist they get made with root. I need to give privileges back to the user.
I need to modify this script to chown the directory and the file. Adding the following does not appear to work for the script.

sudo chown /Users/"$currentUser" /Users/"$currentUser"/FOLDER/FILE

You need to add the command "echo $currentuser" or echo "$currentUser" as you set at the beginning of your script. What I posted above works every time it's ran either automatically after enrollment, or when someone runs the policy through Self Service. Without the echo command, the rest of the script doesn't work, since it has no idea who "currentUser" is.
