feat(assert): add assert_file_permissions#745
Merged
Conversation
Assert a file's octal permission mode (e.g. 644, 0755). A leading zero is optional and modes are compared numerically, so 0755 and 755 are equal. Reads the mode portably via GNU stat with a BSD stat fallback (macOS). Closes #742
Git Bash fakes POSIX permissions, so chmod/stat cannot reproduce exact modes.
