Step-by-Step Solution
Solution:
Step 1: Understand options to exclude binary files
The-Ioption tells grep to ignore binary files during recursive search.Step 2: Evaluate other options
grep -r 'config' /etc --binary-files=text changes binary file handling but may still show binary content; C excludes files by extension but not all binaries; D excludes directories named 'bin' but not binary files.Final Answer:
grep -rI 'config' /etc -> Option DQuick Check:
-I skips binary files in recursive grep [OK]
Quick Trick: Use -I to skip binary files in recursive grep [OK]
Common Mistakes:
- Confusing --exclude-dir with binary file exclusion
- Not using -I to skip binaries
- Assuming --binary-files=text excludes binaries
