Get file name from URL using Lua

Question

How do I get the file name from a URL using Lua string manipulations.

I have this url

https://thisisarandomsite.com/some_dir/src/blah/blah/7fd34a0945b036685bbd6cc2583a5c30.jpg

And I want to get the 7fd34a0945b036685bbd6cc2583a5c30.jpg, it can be a random site so the site name is not static.

Try this:

local str = "https://thisisarandomsite.com/some_dir/src/blah/blah/7fd34a0945b036685bbd6cc2583a5c30.jpg"
local name = str:match( "([^/]+)$" )

You can customise the match pattern from this guide.

This pattern may be slightly simpler to understand: ".+/(.*)$". – Cornwall
