Code

rustc doc

Reproduction Steps

I was trying to use rustc doc on a machine without a browser and I thought I could just pipe the output to curl and that's where I think things broke, previously it was "opening docs in browser" now it is "couldn't read doc: No such file or directory (os error 2)"

Expected Outcome

read the book in terminal

Actual Output

$ rustc doc
error: couldn't read `doc`: No such file or directory (os error 2)
error: aborting due to 1 previous error

Version

rustc 1.89.0 (2948388 2025年08月04日)

Additional Details

also please someone affirm this happens and I am not stupid going around piping things to curl like i did here ;)
