 ### Rationale:
 
-You are using the interpolated string Bashism `$'..'` in a script that declares itself as POSIX sh (e.g. via `#!/bin/sh`).
+ANSI-C quoting, `$'..'`, is a `bash` extension, which is not supported by POSIX `sh`.
 
 To ensure the script runs correctly on other systems, either switch to Bash, or rewrite it in a POSIX compatible way.
