❌ Top 10 Common Mistakes in Writing Scripts

❌ Top 10 Common Mistakes in Writing Scripts 1. Hardcoding Values Using fixed paths, IPs, or credentials inside the script. ✅ Use variables or config files instead. 2. Missing Input Validation Assuming user input or arguments are always correct. ✅ Always check for type, format, and range. 3. No Error Handling Ignoring exceptions or command failures. ✅ Use try/catch, if [ $? -ne 0 ], or similar. 4. Not Cleaning Up Temporary Files Leaving behind unused logs, temp data, or cache. ✅ Add cleanup functions or use trap in shell scripts. 5. Not Checking Command Return Codes Continuing the script even when a step fails. ✅ Always check exit codes before moving forward. 6. Poor Naming Conventions Using vague variable or function names (x, temp, data1). ✅ Use descriptive and consistent naming. 7. Infinite or Uncontrolled Loops Forgetting loop conditions or exit criteria. ✅ Always define clear limits and break conditions. 8. Lack of Documentation No comments, no usage instructions. ✅ Add inline comments and a help section (--help flag). 9. Storing Passwords in Plaintext Writing credentials directly in the code. ✅ Use environment variables or secure vaults. 10. Not Testing Before Deployment Running scripts directly in production without testing. ✅ Always test in a sandbox or staging environment first.
