The -type f argument specifies returning files as results. We are working inside our test directory and the “.” indicates to search the current directory. Use find to search for any file larger than 100MB in the current directory. We can also use the find command in combination with the -size argument specifying a size threshold where any file larger than specified will be returned.\ġ.
