I am trying to get black arch repo on an arch install and ran into this

Is this something Id edit in vim? Very new to this much tweaking so the learning curve is still steep for me. Just an old man going back to school.

$ curl -fsSL https://blackarch.org/strap.sha256

this part does not download a sha256 checksum but the webpage itself (you can check by going to the link in a web browser). where'd you get the command from?

It was in some forum that had a few years a responses for getting the repo. It matched what google spit out when I googled it and I tried it.

you should probably follow the up to date instructions on the blackarch website then. they have a section dedicated to installing it on top of arch linux.
