ever work on a non-gnu box? (old solaris, *bsd, stock os x, etc.) there's a decent chance they don't have -r at all.
*BSDs have (=> OS X probably too).
Solaris, HP-UX and OpenServer have not.
AIX is weird:
> -r Searches directories recursively. By default, links to directories are followed.
> -R Searches directories recursively. By default, links to directories are not followed.
Isn't the AIX behavior the one POSIX specifies?
Looking at MattJ100's link (http://pubs.opengroup.org/onlinepubs/009695399/utilities/gre...), it seems like POSIX grep actually does not have any recursion.
Hence, only lubutu's comment ("-R is the recursion flag for ls, cp, rm, etc") is true, while _delirium ("-R is the POSIX-standard flag for recursive grep") is wrong, which means AIX is free to do whatever it wants with both the -r and the -R flags.
That would be kind of perverse given how cp behaves for -r and -R
