Restore Changed System Files on Linux
Our Linux systems can serve a number of purposes and host a number of applications, services, and general infrastructure. Regardless of purpose, however, we will be working with files, most of which dictate whether the prior will work -- or work the way we expect. In this lab, we explore methods of restoring these changed files when necessary. _This course is not approved or sponsored by Red Hat._
