I'm trying to make a bash script to automatically update plugin files. This problem is complicated due to not having time stamps enabled on the Umod web server. Getting the "Last-Modified" header of the files would be much easier than how I currently have to download the file then compare it to the current file. This means downloading every plugin every time the script is ran. Due to that I have to also add a sleep in the command otherwise the web server starts blocking requests due to flooding.I'm asking if anyone has a better way to do this in bash scripts. I restart my server daily and would like to add this function.

If you are looking at automating, I'd suggest using the JSON API we provide, not headers.

Examples:

https://umod.org/plugins/search.json?query=&page=1&sort=title&sortdir=asc&filter=&author=
https://umod.org/plugins/absolut-gifts.json

I would not recommend blindly updating though.

Thanks. I'll look into it.
