## CLI commands¶
¶
You can start sessions, pipe content, resume conversations, and manage updates with these commands:¶
¶
| Command | Description | Example |¶
| :------------------------------ | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :---------------------------------------------------------- |¶
| `claude` | Start interactive session | `claude` |¶
| `claude "query"` | Start interactive session with initial prompt | `claude "explain this project"` |¶
| `claude -p "query"` | Query via SDK, then exit | `claude -p "explain this function"` |¶
| `cat file \| claude -p "query"` | Process piped content | `cat logs.txt \| claude -p "explain"` |¶
| `claude -c` | Continue most recent conversation in current directory | `claude -c` |¶
| `claude -c -p "query"` | Continue via SDK | `claude -c -p "Check for type errors"` |¶
| `claude -r "<session>" "query"` | Resume session by ID or name | `claude -r "auth-refactor" "Finish this PR"` |¶
| `claude update` | Update to latest version | `claude update` |¶
| `claude auth login` | Sign in to your Anthropic account. Use `--email` to pre-fill your email address, `--sso` to force SSO authentication, and `--console` to sign in with Anthropic Console for API usage billing instead of a Claude subscription | `claude auth login --console` |¶
| `claude auth logout` | Log out from your Anthropic account | `claude auth logout` |¶

| `claude auto-mode defaults` | Print the built-in [auto mode](/en/permission-modes#eliminate-prompts-with-auto-mode) classifier rules as JSON. Use `claude auto-mode config` to see your effective config with settings applied | `claude auto-mode defaults > rules.json` |¶
| `claude mcp` | Configure Model Context Protocol (MCP) servers | See the [Claude Code MCP documentation](/en/mcp). |¶
| `claude plugin` | Manage Claude Code [plugins](/en/plugins). Alias: `claude plugins`. See [plugin reference](/en/plugins-reference#cli-commands-reference) for subcommands | `claude plugin install code-review@claude-plugins-official` |¶
| `claude remote-control` | Start a [Remote Control](/en/remote-control) server to control Claude Code from Claude.ai or the Claude app. Runs in server mode (no local interactive session). See [Server mode flags](/en/remote-control#server-mode) | `claude remote-control --name "My Project"` |¶
¶
## CLI flags¶
¶
Customize Claude Code's behavior with these command-line flags:¶
¶
| Flag | Description | Example |¶
| :---------------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------------------------------------- |¶
| `--add-dir` | Add additional working directories for Claude to read and edit files. Grants file access; most `.claude/` configuration is [not discovered](/en/permissions#additional-directories-grant-file-access-not-configuration) from these directories. Validates each path exists as a directory | `claude --add-dir ../apps ../lib` |¶
| `--agent` | Specify an agent for the current session (overrides the `agent` setting) | `claude --agent my-custom-agent` |¶
| `--agent-teams` | Enable experimental [agent teams](/en/agent-teams). Makes the `SendMessage`, `TeamCreate`, and `TeamDelete` tools available. Equivalent to `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` | `claude --agent-teams` |¶
| `--agents` | Define custom subagents dynamically via JSON. Uses the same field names as subagent [frontmatter](/en/sub-agents#supported-frontmatter-fields), plus a `prompt` field for the agent's instructions | `claude --agents '{"reviewer":{"description":"Reviews code","prompt":"You are a code reviewer"}}'` |¶
| `--allow-dangerously-skip-permissions` | Add `bypassPermissions` to the `Shift+Tab` mode cycle without starting in it.

### System prompt flags¶
¶
Claude Code provides four flags for customizing the system prompt. All four work in both interactive and non-interactive modes.¶
¶
| Flag | Behavior | Example |¶
| :---------------------------- | :------------------------------------------ | :------------------------------------------------------ |¶
| `--system-prompt` | Replaces the entire default prompt | `claude --system-prompt "You are a Python expert"` |¶
| `--system-prompt-file` | Replaces with file contents | `claude --system-prompt-file ./prompts/review.txt` |¶
| `--append-system-prompt` | Appends to the default prompt | `claude --append-system-prompt "Always use TypeScript"` |¶
| `--append-system-prompt-file` | Appends file contents to the default prompt | `claude --append-system-prompt-file ./style-rules.txt` |¶
¶
`--system-prompt` and `--system-prompt-file` are mutually exclusive. The append flags can be combined with either replacement flag.¶
¶
For most use cases, use an append flag. Appending preserves Claude Code's built-in capabilities while adding your requirements. Use a replacement flag only when you need complete control over the system prompt.¶
