How to remove directories safely?

To remove directories safely, you can use the rm command with the -i option, which prompts you for confirmation before each deletion. Here’s how to do it:

For an empty directory:
Use rmdir for empty directories:
```
rmdir -i directory-name
```
For non-empty directories:
Use rm with the -r (recursive) and -i (interactive) options:
```
rm -ri directory-name
```

This way, you will be asked to confirm each file and directory deletion, helping to prevent accidental loss of important data. Always double-check the directory name before confirming the deletion.
