Checkup is a command line tool that checks if a simple html website has been updated
Keep the url of the sites in the file list_of_sites
For example:
https://ozwrites.com/
https://teachyourselfcs.com/
https://sive.rs/
Then run the following command:
source main.sh
In case the 2nd page got some update, you will have:
The site: https://teachyourselfcs.com/ has been updated
TODO: Switch curl command to just get the last-modified field
