I encountered this fun TIL while troubleshooting Linux write permissions

## TL;DR
Don't do this (unless you want misleading test results):
```shell
λ sudo -u node-exporter echo 'Hello, world' >/var/lib/textfile-exporter/test.prom
```
Do this:
```shell
λ echo 'Hello, world' | sudo -u node-exporter tee /var/lib/textfile-exporter/test.prom
```
