  6. # option update_script '/usr/lib/ddns/update_sample.sh'
  7. #
  8. # the script is parsed (not executed) inside send_update() function
  9. # of /usr/lib/ddns/dynamic_dns_functions.sh
  10. # so you can use all available functions and global variables inside this script
  11. # already defined in dynamic_dns_updater.sh and dynamic_dns_functions.sh
  12. #
  13. # It make sence to define the update url ONLY inside this script
  14. # because it's anyway unique to the update script
  15. # otherwise it should work with the default scripts
  16. #
  17. # the code here is the copy of the default used inside send_update()
