- For seeing progress when copying files, use `pv`, [`pycp`](https://github.com/dmerejkowsky/pycp), [`progress`](https://github.com/Xfennec/progress), `rsync --progress`, or, for block-level copying, `dd status=progress`.
- Use `shuf` to shuffle or select random lines from a file. - Use `shuf` to shuffle or select random lines from a file.
- Know `sort`'s options. For numbers, use `-n`, or `-h` for handling human-readable numbers (e.g. from `du -h`). Know how keys work (`-t` and `-k`). In particular, watch out that you need to write `-k1,1` to sort by only the first field; `-k1` means sort according to the whole line. Stable sort (`sort -s`) can be useful. For example, to sort first by field 2, then secondarily by field 1, you can use `sort -k1,1 | sort -s -k2,2`. - Know `sort`'s options.
