Today I learned that you can use split fields based on a character (`t`, `--field-separator=`) and use several of those fields (`-k`, `--key=`) for sorting.
So, for sorting numerically a list of `Sys-Req-nnnn` requirements that is in the clipboard, I can use the following command to make sure I get them sorted, and uniquely listed:
```bash
pbpaste | sort -t \- -k 3 -n | uniq
```
