Unclear Which checks rely on this matching for cp and mv is not settled.
What
When Claude Code looks at a shell command, it tidies the command name before matching it, ignoring letter case and a trailing .exe. This used to apply only to tee. It now also applies to cp (copy files) and mv (move files), so CP, cp.exe and cp are treated alike.
Why
This likely affects how cp and mv are matched in permission or safety checks, so a different spelling of the command is not treated as a different command.
