Hello, manpage grep(1) describes the difference between -r and -R options thus:
-r, --recursive
Read all files under each directory, recursively, following
symbolic links only if they are on the command line. Note
that if no file operand is given, grep searches the working
directory. This is equivalent to the -d recurse option.
-R, --dereference-recursive
Read all files under each directory, recursively. Follow all
symbolic links, unlike -r.
It seems to me that outside of this advertised difference in
following/non-following symlinks, -R option also makes grep to
search through hidden directories. Is it so? Wouldn’t it be a
good idea to put it into a manpage?
Best,
Matěj Cepl
