Reset Linux Home directory permissions based on /etc/passwd

reset_home_directory_permissions.sh

#!/bin/bash

chown root:root /home

chmod 755 /home

USERS=$(grep '/home' /etc/passwd | tr "\n" "\n")

for USER in $USERS
do
    IFS=":" read -ra DETAILS <<< "$USER"

    $(chown -R ${DETAILS[0]}:${DETAILS[0]} ${DETAILS[5]})

    $(chmod -R 750 ${DETAILS[5]})
done

If you are using a custom system that has home directories elsewhere, simply substitute /home for your home directories directory (e.g. /organisation/websites)
