  • -type f: Specifies that you’re looking for regular files.
  • -size +100M: Filters files that are larger than 100 megabytes. Adjust this value as per your requirements.
  • -exec du -sh {} \;: Executes the du -sh command on each found file to display its size in a human-readable format.
  • 2>/dev/null: Redirects any error messages to /dev/null to suppress them.
  • sort -rh: Sorts the output in a reverse human-readable format to display the largest files first.
  • head -n 10: Displays only the first 10 lines of the output, which will be the largest files.
