Syncthing: script to MOVE the latest version of all files from a given folder to a target folder

This is useful in case you've mistakenly deleted a very large folder and it takes forever to restore the files via "file copy". In this case, we're literally MOVING the old version files to the target location! So be careful, this cannot be reverted!

Usage:

./syncthing-restore-version.sh srcFolder dstFolder

Example:

./syncthing-restore-version.sh "My Pictures/.stversions" "My Pictures/restored versions"

NOTE: you should run this script as the "sc-syncthing" user to avoid file permission issues (See runAsSyncthing.sh)

runAsSyncthing.sh

#!/bin/bash
# Script to run a given bash command as another user hard-coded to "sc-syncthing"

args=''
for arg in "$@"; do
	args="$args $(printf %q "$arg")"
done
sudo su -s /bin/bash -c "$(printf %q "$args" | xargs)" sc-syncthing
