cp: -r or -R? The difference explained
Original: cp: -r or -R?
A developer blog post examines whether the Unix copy command's recursive flag should be written as lowercase -r or uppercase -R. The two flags have subtly different histories and behaviours across POSIX systems, and the post walks through which one is portable and safe to use in scripts.
Why now: It is a practical, debate-prone Unix detail that developers enjoy arguing about and testing on their own systems.
