Yeah, either cd into the directory first, or pass it to find. But it’s like 
tar: I can never remember in which order I need to feed stuff to find. One 
relevant addition could be -xdev, to have find halt at file system 
boundaries. So:

find /path/to/dir -xdev -type f -! -type l …

I used the `` in the mail text as a kind of hint: “everything between is a 
command”. So when you paste that into the terminal, it is executed, and the 
result of it is substituted. Meaning: the command’s output is taken as the 
new input and executed. And since the first word of the output was “2”, you 
get that error message. Sorry about the confusion.

I built a wrapper script around it, to which I pass the directory I want to 
read (usually the root of a removable media). The script creates a new text 
file, with the current date and the dircetory in its name, and compresses it 
at the end. This allows me to diff those files in vim and see what changed 
over time. It also updates a symlink to the current version for quick access 
via bash alias.
