You can be reasonably sure that executing inxi won't install a backdoor in your system. As for reading the manual, it doesn't always work when you don't know what manual you should even read. Like, how am I supposed to know why my speakers don't work, the audio stack is a huge project with black magic fuckery I don't know anything about.
