synchronise local directories over ssh

The following command works great for me for a single file:

scp [email protected]:foobar.txt /some/local/directory

What I want to do is do it recursive (i.e. for all subdirectories / subfiles of a given path on server), merge folders and overwrite files that already exist locally, and finally downland only those files on server that are smaller than a certain value (e.g. 10 mb).

How could I do that?

Use rsync.

Your command is likely to look like this:

rsync -az --max-size=10m [email protected]:foobar.txt /some/local/directory

-a (archive mode - the sync is recursive, transfers ownership, attributes, symlinks among other things) -z (compresses transfer)

--max-size (only copies files up to a certain size)

There are many more flags which may be suitable. Checkout the docs for more details - http://linux.die.net/man/1/rsync

First option: use rsync.

Second option, and it's not going to be a one liner, but can be done in three or four lines:

Create a tar archive on the remote system using ssh. Copy the tar from remote system with scp. Untar the archive locally.

If the creation of the archive gets a bit complicated and involves using find and/or tar with several options it is quite practical to create a script which would do that locally, upload it on the server with scp, and only then execute remotely with ssh.
