Linux CLI - Searching and Finding
You want to find all files under /home/user/projects containing the word 'fixme' but exclude any files in node_modules subfolders. Which command achieves this?
You want recursive search for 'fixme' but skip directories named 'node_modules'.
Step 2: Use correct grep option to exclude directories
The --exclude-dir=node_modules option tells grep to skip those folders during recursive search.
Step 3: Check other options
grep -r 'fixme' /home/user/projects | grep -v node_modules filters output but still searches inside node_modules, which is inefficient. grep -r --exclude='node_modules' 'fixme' /home/user/projects excludes files named 'node_modules' not directories. grep -r --exclude-dir='fixme' /home/user/projects excludes directories named 'fixme' which is wrong.
Final Answer:
grep -r --exclude-dir=node_modules 'fixme' /home/user/projects -> Option B
Quick Check:
Use --exclude-dir to skip folders in recursive grep [OK]
Quick Trick:Use --exclude-dir to skip folders during recursive grep [OK]
