### Handle Shell Detection Failure

Source: https://pypi.org/project/shellingham

Wrap the detect_shell call in a try-except block to gracefully handle cases where the shell cannot be detected. This example shows how to catch ShellDetectionFailure and provide a default shell.

```python
try:
    shell = shellingham.detect_shell()
except shellingham.ShellDetectionFailure:
    shell = provide_default()
```

--------------------------------

### Provide Default Shell Implementation

Source: https://pypi.org/project/shellingham

A sample implementation for providing a default shell based on the operating system. It checks for POSIX and Windows environments and uses environment variables like SHELL or COMSPEC.

```python
import os

def provide_default():
    if os.name == 'posix':
        return os.environ['SHELL']
    elif os.name == 'nt':
        return os.environ['COMSPEC']
    raise NotImplementedError(f'OS {os.name!r} support not available')
```

### Detect Current Shell

Source: https://pypi.org/project/shellingham

Use this function to detect the current shell environment. It returns a tuple containing the shell name and the command used to run it. Requires importing the shellingham library.

```python
import shellingham

print(shellingham.detect_shell())
```
