### Define Custom bash-dash Commands (Advanced)

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

Adds custom commands with more control, specifying the URL, HTTP method (GET, POST, etc.), and an optional TEST-URL for testing webhook calls.

### Define Custom bash-dash Commands (Simple)

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

```

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

### Configure Terminal to Use New Bash

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

Register the new Bash executable path in the system's list of valid shells and then set it as your default login shell. This ensures that new terminal sessions automatically start with the upgraded Bash.

```bash
$ sudo bash -c 'echo /usr/local/bin/bash >> /etc/shells'
$ chsh -s /usr/local/bin/bash
```

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

### Check Current Bash Version

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

Verify the currently installed Bash version on your macOS system. This helps identify if an upgrade is necessary due to limitations or security concerns of older versions.

```bash
$ bash --version
3.2.53(1)-release
```

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

### Add New Bash to PATH

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

Update your shell's PATH environment variable to include the directory where the newly installed Bash executable resides. This allows your system to find and use the upgraded Bash version.

```bash
# add to .bash_profile (recommended) or .bashrc
export PATH="/usr/local/bin:$PATH"
```

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

### Call bash-dash Commands

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

### Call Test Webhook

Source: https://github.com/n8n-io/bash-dash/blob/main/README.md

```bash
- your_command --test
```

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