# CLI Reference
Task CLI commands have the following syntax:
```shell
task [--flags] [tasks...] [-- CLI_ARGS...]
```
:::tip
If `--` is given, all remaining arguments will be assigned to a special
`CLI_ARGS` variable
## Flags
:::

| `-d` | `--dir` | `string` | Working directory | Sets directory of execution. |
| `-n` | `--dry` | `bool` | `false` | Compiles and prints tasks in the order that they would be run, without executing them. |

## Exit Codes
Task will sometimes exit with specific exit codes. These codes are split into
four groups with the following ranges:
- Success (0)
- General errors (1-99)
- Taskfile errors (100-199)
- Task errors (200-299)
A full list of the exit codes and their descriptions can be found below:
| Code | Description |
|------|---------------------------------------------------------------------|
| 0 | Success |
| 1 | An unknown error occurred |
| 100 | No Taskfile was found |
| 101 | A Taskfile already exists when trying to initialize one |
| 102 | The Taskfile is invalid or cannot be parsed |
| 103 | A remote Taskfile could not be downloaded |
| 104 | A remote Taskfile was not trusted by the user |
| 105 | A remote Taskfile was could not be fetched securely |
| 106 | No cache was found for a remote Taskfile in offline mode |
| 107 | No schema version was defined in the Taskfile |
| 200 | The specified task could not be found |
| 201 | An error occurred while executing a command inside of a task |
| 202 | The user tried to invoke a task that is internal |
| 203 | There a multiple tasks with the same name or alias |
| 204 | A task was called too many times |
| 205 | A task was cancelled by the user |
| 206 | A task was not executed due to missing required variables |
| 207 | A task was not executed due to a variable having an incorrect value |
These codes can also be found in the repository in
[`errors/errors.go`](https://github.com/go-task/task/blob/main/errors/errors.go).
:::info
When Task is run with the `-x`/`--exit-code` flag, the exit code of any failed
commands will be passed through to the user instead.

## JSON Output
When using the `--json` flag in combination with either the `--list` or
`--list-all` flags, the output will be a JSON object with the following
structure:
```json
{
"tasks": [
{
"name": "",
"desc": "",
"summary": "",
"up_to_date": false,
"location": {
"line": 54,
"column": 3,
"taskfile": "/path/to/Taskfile.yml"
}
}
// ...
],
"location": "/path/to/Taskfile.yml"
}
```
