Re: [PATCH] adding two new options to 'cp'

I'm tired of trying to use rsync or gcp (which doesn't like symlinks often) to copy trees of files/directories using hard links, so I added the gcp-ish options -a and -l.

-a is 'archive' mode, which is just a quick form of -PpR.
-l is 'link' mode, where regular files get hard linked instead of copied.

So, you can mimic an entire tree with something like:

cp -al /from/ /to/


I've always used:
find . -depth |cpio -pdlmv $dest
(fully portable) but your addition can't hurt (well it might make the larger program load a bit slower
but it isn't that much.)


and it's fast too!

Patch is against 6-STABLE, but works well on 7-CURRENT as well.

Patch is here (with man page edits):
http://www.googlebit.com/freebsd/patches/cp-patch

cd /tmp/
fetch http://www.googlebit.com/freebsd/patches/cp-patch
cd /usr/src/
patch < /tmp/cp-patch
cd bin/cp
make && make install

Patch was done for rsnapshot users mainly (there are quite a few of us).

Comments? Flames? Committers willing to commit?

Eric
