Try this instead:
find . -type f -print0 | wc --files0-from=-
If you have a specific need that is often repeated then making a shell
script, function or alias to encapsulate this into a shorter typed
command might be useful.
I would like to file a wishlist that -r be removed from grep which
added it recently. Really! It has been a source of a very long list
of bugs in that program.
Seriously there isn't a need for *every utility* to add directory
traversal (file finding) routines. It isn't needed and it creates
bloated and bug prone code. It violates the spirit of the Unix
philosophy.
For example it isn't simply -r,--recursive. Once that is added then
--exclude, --exclude-from, --exclude-dir and --include, special rules
for file names "**" and 'skip', 'read', and 'devices' and all rest of
the framework that is needed to support it. It isn't small. It isn't
simple. It can't be implemented uniformly. Most importantly it both
isn't needed and isn't desired.
Instead please learn to use 'find' for directory traversal. It works
generically with the entire set of file operation utilities. It is a
very useful for more programs than simply 'wc'. Being able to use
'find' makes one much more powerful and productive.
