# sync_mv

## Overview
Generates a script containing `mkdir` and `mv` commands that moves the files in the `dst` folder to
match the file structure of the `src` folder.

This utility is helpful for avoiding file copy (often from a remote computer) when using `rsync` and
the files in the `src` folder have been moved:

1. It detects a file that have been moved in `src` that already existing in `dst`, and generate a
`mv` command to move the file.

2. It detects duplication with file size and modified date. So it's assuming `rsync` is copying the
file attributes over. E.g., using `rsync -a`.

3. By default files smaller than 1MB is ignored, since copying them with `rsync` does not add much
time. The threshold can be controlled by the `--min-file-size` flag.

4. All symlinks are ignored.

Command:

```bash
sync_mv --action digest --folder source_folder --min-file-size 1000000 > src.json
# or: ssh user@host_ip '/home/user/sync_mv --action digest --folder source_folder --min-file-size 1000000' > src.json
sync_mv --action digest --folder destination_folder --min-file-size 1000000 > dst.json
sync_mv --action diff --src src.json --dst dst.json > diff.txt
```

The above command generates a diff.txt containing the command to run. You can inspect the file and
run it and then optionally sync the folders with `rsync`. E.g.,

```bash
bash diff.txt
rsync -avh source_folder destination_folder
```
