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
|
||
|
|
```
