# *  chmod 751 updatevpnbookpass.1d.sh
# Some commands of the script needs admin rights.
# It can be done adding the name of the script to the parameter file 'sudoers', giving the possibility to anybody to execute it:

# *  (enter the root password)
# *  sudo visudo
# *  <your user>      ALL= NOPASSWD: <your path>/updatevpnbookpass.1d.sh
# (This line is to add in the User privilege specification block )
# (where <your user> is your session account
# (and <your path> is the directory where you place your bitbar plugins)
# *  :wq! (to leave visudo)
