Add / updates a password for a single user in .htpasswd file(s).
Example usage: $ sudo ./update_htpasswd.sh --name="Bond" --password="Secret Squirrel 007"

  • By default it will run against all .htpasswd files found under the configured webroot, but can also target specific files using the --files= arg.
  • Requires sudo to account for varying permissions. Comment out ln 18 if not needed.
