## TerminalToolkit

```python
class TerminalToolkit(BaseToolkit):
```

A toolkit for terminal operations across multiple operating systems.

This toolkit provides a set of functions for terminal operations such as
searching for files by name or content, executing shell commands, and
managing terminal sessions.

**Parameters:**

- **timeout** (Optional[float]): The timeout for terminal operations.
- **shell_sessions** (Optional[Dict[str, Any]]): A dictionary to store shell session information. If None, an empty dictionary will be used. (default: :obj:`{}`)
- **working_dir** (str): The working directory for operations. If specified, all execution and write operations will be restricted to this directory. Read operations can access paths outside this directory.(default: :obj:`"./workspace"`)
- **need_terminal** (bool): Whether to create a terminal interface. (default: :obj:`True`)
- **use_shell_mode** (bool): Whether to use shell mode for command execution. (default: :obj:`True`)
- **clone_current_env** (bool): Whether to clone the current Python environment.(default: :obj:`False`)
- **safe_mode** (bool): Whether to enable safe mode to restrict operations. (default: :obj:`True`)

**Note:**

Most functions are compatible with Unix-based systems (macOS, Linux).
For Windows compatibility, additional implementation details are
needed.

pattern within a directory. It uses `find` on Unix-like systems and
`dir` on Windows.

**Parameters:**

<a id="camel.toolkits.terminal_toolkit.TerminalToolkit.shell_exec"></a>

### shell_exec

```python
def shell_exec(
    self,
    id: str,
    command: str,
    interactive: bool = False
):
```

Executes a shell command in a specified session.

This function creates and manages shell sessions to execute commands,
simulating a real terminal. It can run commands in both non-interactive
(capturing output) and interactive modes. Each session is identified by
a unique ID. If a session with the given ID does not exist, it will be
created.

**Parameters:**

- **id** (str): A unique identifier for the shell session. This is used to manage multiple concurrent shell processes.
- **command** (str): The shell command to be executed.
- **interactive** (bool, optional): If `True`, the command runs in interactive mode, connecting it to the terminal's standard input. This is useful for commands that require user input, like `ssh`. Defaults to `False`. Interactive mode is only supported on macOS and Linux. (default: :obj:`False`)

**Returns:**

  str: The standard output and standard error from the command. If an
error occurs during execution, a descriptive error message is
returned.

**Note:**

When `interactive` is set to `True`, this function may block if the
command requires input. In safe mode, some commands that are
considered dangerous are restricted.

<a id="camel.toolkits.terminal_toolkit.TerminalToolkit.shell_view"></a>

### shell_view

```python
def shell_view(self, id: str):
```

View the full output history of a specified shell session.

Retrieves the accumulated output (both stdout and stderr) generated by
commands in the specified session since its creation. This is useful
for checking the complete history of a session, especially after a
command has finished execution.

**Parameters:**

- **id** (str): The unique identifier of the shell session to view.

**Returns:**

  str: The complete output history of the shell session. Returns an
error message if the session is not found.

<a id="camel.toolkits.terminal_toolkit.TerminalToolkit.shell_wait"></a>

### shell_wait

```python
def shell_wait(self, id: str, seconds: Optional[int] = None):
```

Wait for a command to finish in a specified shell session.

Blocks execution and waits for the running process in a shell session
to complete. This is useful for ensuring a long-running command has
finished before proceeding.

**Parameters:**

- **id** (str): The unique identifier of the target shell session.
- **seconds** (Optional[int], optional): The maximum time to wait, in seconds. If `None`, it waits indefinitely. (default: :obj:`None`)

**Returns:**

  str: A message indicating that the process has completed, including
the final output. If the process times out, it returns a
timeout message.

```python
def shell_write_to_process(
    self,
    id: str,
    input: str,
    press_enter: bool
):
```

Write input to a running process in a specified shell session.

Sends a string of text to the standard input of a running process.
This is useful for interacting with commands that require input. This
function cannot be used with a command that was started in
interactive mode.

**Parameters:**

- **id** (str): The unique identifier of the target shell session.
- **input** (str): The text to write to the process's stdin.
- **press_enter** (bool): If `True`, a newline character (`\n`) is appended to the input, simulating pressing the Enter key.

**Returns:**

  str: A status message indicating whether the input was sent, or an
error message if the operation fails.

### shell_kill_process

```python
def shell_kill_process(self, id: str):
```

Terminate a running process in a specified shell session.

Forcibly stops a command that is currently running in a shell session.
This is useful for ending processes that are stuck, running too long,
or need to be cancelled.

**Parameters:**

- **id** (str): The unique identifier of the shell session containing the process to be terminated.

**Returns:**

  str: A status message indicating that the process has been
terminated, or an error message if the operation fails.

```

Pause the agent and ask a human for help with a command.

This function should be used when the agent is stuck and requires
manual intervention, such as solving a CAPTCHA or debugging a complex
issue. It pauses the agent's execution and allows a human to take
control of a specified shell session. The human can execute one
command to resolve the issue, and then control is returned to the
agent.

**Parameters:**

- **id** (str): The identifier of the shell session for the human to interact with. If the session does not exist, it will be created.

**Returns:**

  str: A status message indicating that the human has finished,
including the number of commands executed. If the takeover
times out or fails, an error message is returned.
