grep searches inside files. find searches for files — it walks a directory tree and lists everything matching your criteria, no matter how deep it's buried. When you know a file exists somewhere but not where, find is the answer.
You'll practice:
find PATH -name — search by exact namefind with wildcards — match patterns like *.log-type f — only files-type d — only directoriesYour projects folder has a small tree: some .txt files, a logs/ folder with .log files, and a src/ folder with Python files nested inside. Move into projects first.
