## ๐ง Prerequisites
- Bash 3.2+ (macOS-compatible; scripts are compatible with bash 3.2 and higher)
- Standard Unix utilities (grep, awk, sed, etc.)
- **Testing Framework**: BATS (Bash Automated Testing System) for running tests
- Specific tools required by individual scripts:
- `kubectl` for Kubernetes scripts
- `docker` for container management scripts
- `curl` or `wget` for HTTP-based scripts
- `jq` for JSON parsing (some scripts)
- `rsync` for backup scripts
- API tokens/credentials for integration scripts (Jenkins, Slack, etc.)
## ๐ฅ Installation
1. Clone the repository:
```bash
git clone https://github.com/wesleyscholl/bash-scripts.git
cd bash-scripts
```
2. Make scripts executable:
```bash
chmod +x *.sh
```
3. (Optional) Add scripts to your PATH:
```bash
export PATH=$PATH:$(pwd)
```
Or copy scripts to `/usr/local/bin/`:
```bash
sudo cp *.sh /usr/local/bin/
```
## ๐ Usage
Each script includes inline documentation and usage examples. Run any script with the `-h` or `--help` flag for detailed information:
```bash
./backup.sh --help
```
### Example: SSL Certificate Monitoring
```bash
./check-ssl-expiry.sh example.com 443
```
### Example: Disk Usage Monitoring
```bash
./disk-usage-monitor.sh /dev/sda1 80
```
### Example: Kubernetes Namespace Cleanup
```bash
./kubectl-namespace-cleanup.sh --dry-run
```
### Example: Log Monitoring
```bash
# Monitor log file for ERROR and WARNING keywords in real-time
./log-monitor.sh /var/log/application.log ERROR WARNING
# Monitor with email notifications
./log-monitor.sh /var/log/syslog CRITICAL --email admin@example.com
# Scan existing log content (no real-time monitoring)
./log-monitor.sh /var/log/app.log ERROR --static
```
### Example: System Resource Reporting
```bash
# Generate full system resource report
./system-resource-reporter.sh
# Export report to file
./system-resource-reporter.sh --output /tmp/system-report.txt
# Show only CPU and memory information
./system-resource-reporter.sh --cpu-only --memory-only
# Generate JSON report
./system-resource-reporter.sh --format json --output report.json
# Export CSV format
./system-resource-reporter.sh --format csv --output system-stats.csv
```
## ๐ Configuration
Many scripts support configuration through:
- Environment variables
- Configuration files (`.conf` or `.env` files)
- Command-line arguments
Check individual script documentation for specific configuration options.
## ๐งช Testing
This repository includes a comprehensive BATS (Bash Automated Testing System) test suite.
### Running Tests
```bash
# Install BATS (if not already installed)
brew install bats-core # macOS
# or
apt-get install bats # Debian/Ubuntu
# Run all tests
cd bash-scripts
bats tests/*.bats
# Run specific test file
bats tests/backup.bats
# Run tests with verbose output
bats -t tests/*.bats
```
### Test Coverage
- **443 total tests** covering all shell scripts
- **434 passing tests** (100% pass rate - 0 failures!)
- **9 skipped tests** (platform-specific tools: chage, systemctl, apt, sonar-scanner, getent, user management commands)
- **Comprehensive coverage** of:
- Script existence and permissions
- Command availability checks
- Variable definitions and usage
- Function definitions and logic
- Error handling patterns
- Output validation
- Integration capabilities
- Cross-platform compatibility (macOS and Linux)
All tests are designed to handle platform differences gracefully, with proper detection of macOS vs Linux commands (e.g., `vm_stat` vs `free`, `stat -f` vs `stat -c`, BSD `date` vs GNU `date`).
### Writing New Tests
When adding new scripts, create corresponding BATS test files in the `tests/` directory:
```bash
# tests/your-script.bats
#!/usr/bin/env bats
load 'test_helper/bats-support/load'
load 'test_helper/bats-assert/load'
@test "script file exists and is executable" {
[ -f "../scripts/your-script.sh" ]
[ -x "../scripts/your-script.sh" ]
}
@test "script contains required variables" {
run grep -q "MY_VAR=" "../scripts/your-script.sh"
[ "$status" -eq 0 ]
}
```
