2. Type claude-code to launch the assistant.
3. To edit a file, use the command: claude-code edit <filename>. Replace <filename> with the path to your file.
4. You can run a command by typing claude-code run <command>. For example, claude-code run ls to list directory contents.

Step 3: Get better results

Pro tip

Instead of typing out long commands repeatedly, create aliases in your shell configuration file (like .bashrc or .zshrc). For example: alias cc='claude-code' allows you to simply type cc edit <filename>.

Common mistake to avoid

Avoid using vague prompts or commands. For example, instead of asking Claude Code to "fix the code," specify exactly what needs changing. This will ensure you get the precise help you need without confusion.
