`pysyslimit` is a light-weight library which can manage the permission in linux system.

## Installation

Just install this package with the pip command

```bash
pip install pysyslimit
```

For further information, take a look at the [Installation Page](https://hansbug.github.io/pysyslimit/main/tutorials/installation/index.html).

## Quick Start

**Please attention that many function in this library need root permission, so It is strongly recommended to run this with root.**

### Take a look at who I am

```python
from pysyslimit import *

if __name__ == "__main__":
    print("current user:", SystemUser.current())
    print("current user's groups:", SystemUser.current().groups)
    print("current group:", SystemGroup.current())

```

The output should be

```text
current user: root
current user's groups: [<SystemGroup root, id: 0>]
current group: root
```

### Get and update the permission of files

```python
from pysyslimit import *

if __name__ == "__main__":
    print(FilePermission.load_from_file("test_file"))

    chmod_del("test_file", "004")
    print(FilePermission.load_from_file("test_file"))

    chmod_add("test_file", "014")
    print(FilePermission.load_from_file("test_file"))

```

The output shall be

```text
rw-rw-r--
rw-rw----
rw-rwxr--
```

### Do calculation between permissions

```python
from pysyslimit import *

if __name__ == "__main__":
    print(FilePermission.loads('463') + FilePermission.loads('615'))
    print(FilePermission.loads('463') | FilePermission.loads('615'))  # the same as +
    print(FilePermission.loads('463') - FilePermission.loads('615'))
    print(FilePermission.loads('463') & FilePermission.loads('615'))

```

The output shall be

```text
rw-rwxrwx
rw-rwxrwx
---rw--w-
r-------x
```
