cp's -r vs -R flag debate resurfaces
Original: cp: -r or -R?
A blog post by developer movq examines a long-standing quirk of the Unix cp command: whether the recursive copy option should be written as lowercase -r or uppercase -R. The two flags have subtly different histories across BSD, GNU and POSIX systems, and the piece walks through what each specification actually guarantees, reigniting a familiar argument among command-line users.
Why now: Programmers enjoy debating small, surprisingly messy details of tools they use daily, and flag portability is a recurring source of confusion.
