@ -447,6 +447,18 @@ A few examples of piecing together commands:
- `fortune`, `ddate`, and `sl`: um, well, it depends on whether you consider steam locomotives and Zippy quotations "useful"
- `watch` lets you run a command repeatedly without re-typing it:
```sh
# Will run every two seconds. The optional
# -d causes it to highlight any changes.
$ watch -d -n 2 'ls -rtlh | tail'
# Keep an eye on your IP address and data transfer
# while troubleshooting your WiFi connection.
watch -d -n 2 ifconfig
```
