+I encountered this fun TIL while troubleshooting Linux write permissions
+issues...
+
+## 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
+```
