-# Real-World Examples
-
-This directory contains practical examples that demonstrate rawk's utility for common data processing tasks.
-
-## Test Files
-
-### `test_system_monitor.rawk` - System Monitoring
-Processes output from common system commands:
-- **df**: Disk usage monitoring with warnings
-- **ps**: Process resource analysis
-- **ls -l**: File categorization and statistics
-
-**Features:**
-- Disk usage alerts (WARNING/CRITICAL thresholds)
-- Process resource monitoring (CPU/MEM usage)
-- File type categorization (DIRECTORY/EXECUTABLE/LARGE/SMALL)
-- Statistical summaries
-
-**Run with:**
-```bash
-awk -f ../../rawk.awk test_system_monitor.rawk | awk -f - ../data/test_data.txt
-```
-
-**Sample Output:**
-```
-DISK: WARNING: /dev/sdb1 (/home) is 90% full
-PROCESS: HIGH CPU: stress (PID: 3456, 25.7% CPU)
-FILE: EXECUTABLE: executable.sh (2048 bytes)
-```
-
-### `test_log_parser.rawk` - Log Parsing
-Processes common log formats:
-- **Apache logs**: Web server access logs
-- **Syslog**: System log entries
-
-**Features:**
-- HTTP status code categorization (SUCCESS/ERROR/REDIRECT)
-- Log level detection (INFO/WARNING/ERROR)
-- Request type classification
-- Error rate calculation
-
-**Run with:**
-```bash
-awk -f ../../rawk.awk test_log_parser.rawk | awk -f - ../data/test_logs.txt
-```
-
-**Sample Output:**
-```
-APACHE: ERROR: 404 - GET /nonexistent.html from 192.168.1.104
-SYSLOG: ERROR: kernel - ERROR: Out of memory
-```
-
-### `test_csv_processor.rawk` - CSV Data Processing
-Processes CSV files with validation:
-- **Email validation**: Basic email format checking
-- **Age categorization**: Group employees by age
-- **Salary statistics**: Calculate averages and ranges
-- **Department analysis**: Employee distribution
-
-**Features:**
-- Data validation and categorization
-- Statistical analysis
-- Report generation
-- Error detection
-
-**Run with:**
-```bash
-awk -f ../../rawk.awk test_csv_processor.rawk | awk -f - ../data/test_employees.csv
-```
-
-**Sample Output:**
-```
-EMPLOYEE: John Smith (ADULT, Engineering) - VALID email, $65000
-Average salary: $73916.7
-Email validity rate: 100%
-```
-
-### `test_data_processing.rawk` - General Data Processing
-General data processing scenarios:
-- Array filtering and manipulation
-- Data aggregation
-- Formatting and reporting
-
-**Run with:**
-```bash
-awk -f ../../rawk.awk test_data_processing.rawk | awk -f -
-```
-
-### `test_mixed.rawk` - Mixed awk/rawk Code
-Demonstrates mixing rawk functions with regular awk code:
-- Line-by-line processing
-- Integration with awk patterns
-- Combined functionality
-
-**Run with:**
-```bash
-awk -f ../../rawk.awk test_mixed.rawk | awk -f - ../data/test_input.txt
-```
-
-## Use Cases
-
-These examples demonstrate rawk's practical applications:
-
-### System Administration
-- Monitor disk usage and alert on thresholds
-- Track process resource consumption
-- Analyze file system contents
-
-### Web Server Management
-- Parse and analyze web server logs
-- Monitor error rates and traffic patterns
-- Identify problematic requests
-
-### Data Analysis
-- Process CSV files with validation
-- Generate business intelligence reports
-- Analyze employee or customer data
-
-### Log Analysis
-- Parse various log formats
-- Identify system issues
-- Generate operational reports
-
-## Data Files
-
-The examples use sample data files in the `../data/` directory:
-- `test_data.txt`: Simulated system command outputs
-- `test_logs.txt`: Sample Apache and syslog entries
-- `test_employees.csv`: Sample employee data
-- `test_input.txt`: Simple input data for mixed tests
