Unknown directives in .shellcheckrc are silently ignored #3591
Description
For bugs with existing features
- Rule Id (if any, e.g. SC1000): SC1107
- My shellcheck version (
shellcheck --versionor "online"): v0.11.0 - The rule's wiki page does not already cover this (e.g. https://shellcheck.net/wiki/SC2086)
- I tried on https://www.shellcheck.net/ and verified that this is still a problem on the latest commit
Here's a snippet or screenshot that shows the problem:
$ shellcheck --rcfile=<(<<< foo=bar) -s sh /dev/nullHere's what shellcheck currently says:
Nothing
Here's what I wanted or expected to see:
In /proc/self/fd/12 line 1:
foo=bar
^-- SC1107 (warning): This directive is unknown. It will be ignored.
similarly to a directive in a script
$ shellcheck -s sh - <<< '# shellcheck foo=bar'
In - line 1:
# shellcheck foo=bar
^-- SC1107 (warning): This directive is unknown. It will be ignored.

Hi! I'd like to work on this issue as my first contribution to ShellCheck. I'll investigate how unknown directives are handled in
.shellcheckrc, add a regression test, and implement a focused fix while preserving the existing behavior for valid directives. I'll run the relevant tests before submitting a pull request. Please let me know if anyone is already working on this or if you have any preferred approach.
