Copy flies on OSX using hard links

[nerbonne]

I'm pretty sure that on Linux I used to be able to copy files and directories using "cp -al dir1 dir2" to make a copy of the directory that only updated the file count but didn't take up any more space on the disk.

However, on OSX Snow Leopard, the cp arguments are way different and this doesn't work. Can anyone tell me how to make copies of entire directories but not use more space on the disk?

The basic command for creating a hard link is the ln command, but that only works on single files.

A shell script using this and the find command could be used to hard-link a directory structure.

Or you could try apropos copy to see what other commands mention copy.
