How can I read the filename from a script?

[bobbykjack]

I currently have a script that stuffs its input into HTML and sends that to the browser using data:text/html. This works OK, but I have some markdown files under a local web server's docroot that I'd like to serve directly. So I'm trying to get the path of the specific file when running a script.

I've looked in both the ENV and $@ but neither contains the file path. Is there another way to get this data?

CotEditor passes the document file path as an argument when the CotEditor script is an UNIX script (= not an AppleScript), and the document is already saved somewhere so that is has a file path.

In case, I’ve also quickly tested it in the latest environment (macOS 15.3 and CotEditor 5.0.8) and confirmed that it still works.

Example in Python

import sys

filepath = sys.argv[1]
print(filepath, file=sys.stderr)

So it does! I hoped that would be the case but, for some reason, I only tested with $0 and didn't check $1.
