Hi folks, Does anyone know how to instruct cron to carry out a command when a connection to the internet is first made after boot? I have a few jobs that only need to be done once per day and require an internet connection e.g downloading the weather forecast and my rss feeds. I’m not always connected to the internet on boot and do not have the computer switched on at the same times every day. Many thanks for any suggestions.
Personally I’d write a script to do whatever it is you want to do, checking first whether the internet connection is working. Said script can check the internet is working, if not, sleep for 10 minute or something, and try again, perhaps giving up after a set number of tries. Said script could also check the date and time of the file downloaded and confirm it is out of date.
Then, have the script execute on bootup by adding it to the startup scripts.
