I'm trying to find the command to delete recursively all Apple Mac generated files such as '._' from the drive. So far I have:

find . -name '._*' -exec rm -rf {} \;

however it doesn't seem to do the trick.

Sorry, this is off-topic. Try superuser.stackexchange.com – Joe Dec 20 '12 at 16:20
    
How is this off topic? Isn't ssh covered here - I've seen several posts for ssh, but none explaining how to achieve the above. – Spencer Mark Dec 20 '12 at 16:39
    
They might have been old questions. Since StackOverflow launched, lots of StackExchanges have sprung up to fill specialisms. Those questions might have appeared before that StackExchange site existed. – Joe Dec 20 '12 at 17:01

What do you observe? – Nicole Hamilton Dec 20 '12 at 17:23

Using the dot as first argument starts in the directory you are currently in.

If you want to find all files beginning with ._ you should use the slash as first parameter so that find starts at the root-directory.

And as some of these files will not be owned by you you might like to use the suso command also.

So the complete command looks like this:

sudo find / -name "._*" -exec rm -rf {} \;

At least for me that always does the trick. Ommiting the -exec part will simply list all files so you might run this first to see whether all files are found you expect

find . ( -name '._*' ) -exec rm {} -rf \; should work

I don't know if it's different in OSX compared to bash.

Macs run Bash and certainly have find although I think it's a bit out of date. The man page says 2008, but I'm sure it'll be sufficiently up to date. – Joe Dec 20 '12 at 23:03

I know: this post is obsolete. Anyway I write here because is the first I found! I had the same problem with a Dropbox account that I used on mac osx, moved now on Windows / Linux Ubuntu. Using bash (mine is the Cygwin64 bash), I typed inside my Dropbox folder:

find . -regex '.+/\._.+' -exec rm {} \;

Note that -rf was removed from above solutions. '._' are supposed to be only files, so do not add too many powers to rm command! ;)

There's now a better way!

See man dot_clean since OS X 10.5.

dot_clean -n . will not just delete the dot underbar files in and below the current directory, it'll merge their information into the parent file if it's not already there (and I infer that you want -n to also delete the dot underbar file if there is no matching native file).
