scp -r ... but leave out (exclude) a specified subdirectory

Here's the directory structure:

/a/
/a/b/
/a/c/

I want to copy everything, EXCEPT for the /a/c/ subdirectory.

scp -rp myserver:/a .      # this will copy everything

Q: How would I specify a directory to leave out in the scp command ?

I don't think you can, but you could use rsync? Something like this:

rsync -a --exclude=a/c myserver:/a .

I think this might be the correct way of doing it so you are still using SSH, I haven't found a way to do it with scp - but using rsync over ssh might resolve it.

rsync -e 'ssh -ax' -av --exclude /a/c myserver:/a .

If you use the -n switch then it will create a dry run of the process:

 rsync -e 'ssh -ax' -av --exclude /a/c -n myserver:/a .

You can use extended globbing as in the example below:

#Enable extglob
shopt -s extglob

cp -rv !(./excludeme/*.jpg) /var/destination
