Auto-sync files or directories over SSH using fs.watch().

would you like to use key-based authentication? [yes/no]

• yes – if they do not already exist, SSH private/public keys will be generated with ssh-keygen to ~/.ssh/sshync and the public one moved to ~/.ssh/authorized_keys on remote host (assumes you have access). Files will be transferred asynchronously.
• no – files will be transferred synchronously and you will have to enter password every time a file changes. files will now be transferred asynchronously and you will now only have to enter password once when sshync is run.

Utilizes simple caching to avoid unnecessary file transfers and to continuously show size difference.

Ignore paths by adding them, one per line, to a file named .sshyncignore in the root source folder.

$ npm install sshync -g

# initialize sshync
# (you might have to type password to transfer public key to remote host)
$ sshync <user@ip[:port]> <source> <destination>
          source:       local source folder.
          destination:  remote destination folder.

First time run output:

$ sshync [email protected] sshync.js /root/sshync/sshync.js
