cd phoenixnebula
pip install -e .
phoenixnebula
```

## Quick Start 🚀

### Basic Commands

```bash
$ echo "Hello, World!"
Hello, World!

$ pwd
/home/user

$ cd Documents

$ ls -la
```

### Background Jobs

Append `&` to run a command in the background:

```bash
$ sleep 100 &
[1] 12345

$ jobs
[1]  Running  sleep 100

$ fg %1
```

### Piping Commands

```bash
$ cat file.txt | grep "search_term" | wc -l
```

### Output Redirection

```bash
$ echo "text" > output.txt          # Write to file
$ echo "text" >> output.txt         # Append to file
$ command 2> errors.txt             # Redirect stderr
$ command 2>> errors.txt            # Append stderr
```

alias ll=ls -la
alias ..=cd ..
alias gs=git status
export PS1="\u@\h \w\$ "
```

### Themes

PhoenixNebula comes with 5 built-in themes. Create custom themes at `~/.phoenixnebula/themes/mytheme.json`:

```json
{
  "name": "My Custom Theme",

  "foreground": "#e0e0e0",
  "cursor_color": "#e0e0e0",
  "black": "#000000",

## Security 🔒

- **No External Dependencies** - Uses only Python standard library
- **Safe Input Handling** - All input is validated and parsed safely using `shlex`
- **No Code Injection** - Never uses `eval()`, `exec()`, or `__import__()`
- **Secure Variable Expansion** - Variables are safely expanded with fallbacks
- **Signal Safety** - Proper signal handling without race conditions
- **Process Isolation** - Background jobs properly isolated using process groups

See [SECURITY.md](SECURITY.md) for detailed security information.

## Troubleshooting 🔧

### Shell Exits Unexpectedly

Check your `~/.phoenixnebularc` file for errors:

```bash
cat ~/.phoenixnebularc
```

### History Not Saving

Ensure the history file location is writable:

```bash
export HISTFILE=~/.phoenixnebula_history
```

### Tab Completion Not Working

Verify Python readline module is available:

```bash
python3 -c "import readline; print('readline available')"
```

### Interactive Programs Not Working Properly

Ensure your terminal emulator supports ANSI escape codes and PTY operations. Try clearing the screen:

```bash
clear
```

### Theme Colors Not Applying

Try resetting the terminal:

```bash
reset
phoenixnebula
```
