Whilst most commandline editors have the ability to edit files on a remote host directly this can get messy sometimes when there are multiple files involved. Mounting the remote folder via SSHFS seems to be more reliable in practical use.

Mount

sudo apt-get install sshfs
sudo addgroup USERNAME fuse
sshfs remoteuser@remotehost:/remote/path /local/mountpath

Unmount

fusermount -u /local/mountpath
