🔍 Basic Grep Guide

• Search for a word in all .md files

grep "keyword" *.md

• Search recursively through directories

grep -r "keyword" .

• Ignore case

grep -i "keyword" filename.md

• Show line numbers

grep -n "keyword" filename.md

• Combine: recursive, case-insensitive, line numbers

grep -rin "keyword" .

• Use regular expressions (careful—this is where it gets spicy)

grep -E "foo|bar" file.md
