SCP User's Guide to Rsync

As part of the 8.0 pre-release announcement, the OpenSSH project stated that they consider the scp protocol outdated, inflexible, and not readily fixed. They then go on to recommend the use of sftp or rsync for file transfer instead. Many users grew up on the scp command, however, and so are not familiar with rsync.

In this situation you have a few options: Spin up a VM using Vagrant The problem here is then I’d have to add a Vagrantfile to this projects repo and either commit it or Gitignore it. This becomes more arduous when you have multiple projects like this since you have to maintain a Vagrantfile per project. So our project looks like this: ./example └── main.c └── Vagrantfile 0 directories, 1 file Use a docker container The problem with docker containers is shared with that of the above solution of ‘Vagrant per project'.
