## Introduction
This is a list of instructions I use frequently in:
- [automated-tasks](https://github.com/frnmst/automated-tasks)
- [fattura-elettronica-reader](https://github.com/frnmst/fattura-elettronica-reader)
- [fpyutils](https://github.com/frnmst/fpyutils)

## pathlib
### Files
| Description | Code | Imports |
|-------------|-------------------------------------------------|---------|
| new file | `pathlib.Path(shlex.quote(path: str)).touch(0o700, exist_ok=True)` | `import pathlib, shlex` |
| remove file | `pathlib.Path(shlex.quote(path: str)).unlink(missing_ok=True)` | `import pathlib, shlex` |
| new directory | `pathlib.Path(shlex.quote(path: str)).mkdir(mode=0o700, parents=True, exist_ok=True)` | `import pathlib, shlex` |
### Paths
| Description | Code | Imports |
|-------------|-------------------------------------------------|---------|
| get last path component from url | `pathlib.Path(urllib.parse.urlsplit(url: str).path).name` | `import pathlib, urllib` |
| get relative path | `pathlib.Path(shlex.quote(path: str)).name` | `import pathlib, shlex` |
| get full path | `str(pathlib.Path(shlex.quote(directory: str), shlex.quote(file: str)))` | `import pathlib, shlex` |
