Revision 6: Automation & File Comparison
Create batch scripts and compare files to master advanced file operations.
Start Interactive Lesson
Welcome to advanced territory! In this final revision, you'll combine command redirection with batch scripting and learn how to compare files for differences. These skills unlock powerful automation capabilities.
Create a batch file with echo redirection!
Challenge 1: Create a Batch Script
Write a command to a batch file using echo and redirection. This creates an executable script that can run the same operations repeatedly without retyping.
By redirecting echo output to a .bat file, you've created a reusable script. Running backup.bat from the command line will execute the stored command automatically — perfect for repetitive tasks.
Challenge 2: Compare Files
Use the fc (file compare) command to identify differences between two files. This is crucial for verification and debugging.
Compare two configuration files!
The output shows differences between files. Each ***** marker indicates where files diverge. This is essential for version control, configuration audits, and detecting data corruption.
