How to update the file server's OS files to the latest version

Run this command as the root user on the master file server (by default, it is the same server as the SynergyCP web server):

file_server_exec() {
    CONT=$(
        docker ps |
        grep scp-bm-pxe-file_api |
        head -n1 |
        awk '{print $NF}'
    )
    docker exec -i ${CONT} $@;
}

run_in_file_server() {
  echo "chown -R deploy:deploy /srv"
  echo "chown -R www:www /srv/tftp/pxelinux.cfg"
}

cd /scp/pxe/file
wget -O - "http://install.synergycp.com/bm/pxe-file-storage.tar.gz" | tar -zxf - -C .
run_in_file_server | file_server_exec /bin/bash

If you have any child file servers, you will want to sync the changes to those using the button on the master file server's edit page in SynergyCP.
