# "composer start-up script to NOT run composer as root user accidentally."

# This is wp-cli.phar start-up script to NOT run wp-cli as root user accidentally.
# This script looks at owner of the current directoy and check if the user actually exists.
# If that is affirmative it would then run wp-cli.phar as user John from the current location.
#
# Instructions:
# put the actual wp-cli.phar into /usr/local/bin so its the path and available
# put this file in the same location and just call it wp

# first section checks if its run as a none root user and if so just executes wp-cli.phar as usual
