# Bash Linux Patterns

> **Command Line Mastery for Local Ops.**

---

## 1. Chaining

- `cmd1 && cmd2`: Run cmd2 only if cmd1 succeeds.
- `cmd1 || cmd2`: Run cmd2 only if cmd1 FAILS.
- `cmd1 ; cmd2`: Run both sequentially irrespective of success.

---

## 2. Process Management

- `ps aux | grep python`: Find your running bots.
- `kill -9 <PID>`: Force kill.
- `jobs`: List background jobs.
- `fg`: Bring background job to foreground.

---

## 3. Scripting Template

For any utility scripts in `scripts/`:

```bash
#!/bin/bash
set -euo pipefail

echo "[INFO] Starting..."

# Check env
if [ ! -f .env ]; then
    echo "[ERROR] Key file missing!"
    exit 1
fi

# Do work
python main.py
```

---

## 4. Permissions

- `chmod +x script.sh`: Make it executable.
