Joplin store

README.md

Directory saver

Save directory data to a local data folder ; see differences ; restore data.

Originally a tool to save Joplin data in case the sync broke/was disastrously told to empty itself.

Can be generalized to a data sync tool.

"Compile" with bash-builder

sync-in.sh

#!/usr/bin/env bash

set -euo pipefail

### Sync Target Folder to Local Folder Usage:help
#
# Put a directory's data into a local ./data directory - for example, in a git repo, or a backup folder
#
#   sync-in.sh
#
# Actions:
#
# backup TARGETDIR
#   take a backup of the target directory
#
# restore TARGETDIR
#   restore the data to the target directory
# 
# diff TARGETDIR
#   show what changes are found in live target directory that are not in the local store
#
