+- As the man page says, `rsync` really is a fast and extraordinarily versatile file copying tool. It's known for synchronizing between machines but is equally useful locally. When security restrictions allow, using `rsync` instead of `scp` allows recovery of a transfer without restarting from scratch. It also is among the [fastest ways](https://web.archive.org/web/20130929001850/http://linuxnote.net/jianingy/en/linux/a-fast-way-to-remove-huge-number-of-files.html) to delete large numbers of files:
 ```sh
 mkdir empty && rsync -r --delete empty/ some-dir && rmdir some-dir
 ```

 - Use `shuf` to shuffle or select random lines from a file.
