*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.
- rbanffy 14y agoIsn't the AIX behavior the one POSIX specifies?
- lmm 14y agoThat would be kind of perverse given how cp behaves for -r and -R
- cschramm 14y agoLooking at MattJ100's link (http://pubs.opengroup.org/onlinepubs/009695399/utilities/grep.html 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.
