How can I rename and move video files based on their folder structure?

You can do this with a simple bash script! First, navigate to the directory containing 'Videos'. Then run the following script to move and rename the files:

```bash
cd Videos

# Bash script to rename and move files
shopt -s nullglob
for path in Friends/*/*/*.mp4; do
[[ -f $path ]] || continue
name=${path#*'/'}
name=${name///_}
name=${name// /_}
mv -- "$path" "Videos/${name}"
done

# Remove empty directories
for dir in Friends/*/; do
rmdir "$dir" 2>/dev/null
done
```

This moves every mp4 file to the main 'Videos' directory and renames it based on the folder structure. Just make sure to back up your files before you run any scripts!

If you prefer an interactive approach, you can use the 'vidir' command from the moreutils package. Here's how:

1. Install moreutils if you haven't already.
2. Navigate to the 'Videos' directory.
3. Run `find . -type f | vidir -`.
4. This opens an editor where you can change filenames directly.

It’s a great way to manage files if you like a bit of visual aid while renaming!

If you're looking for a more straightforward way, try the `rename` command if you're on Linux. It's pretty handy for batch renaming files. You can easily rename files using:

```bash
rename 's/Friends/(.*)/(.*)/(Friends_$1_$2)/' Videos/*/*.mp4
```

This uses a Perl regex to rename the files as you want. Just ensure you install it first, as it's part of the util-linux package. It can save you tons of time when renaming files!
