Join Mike Meyers for an in-depth discussion in this video Linux file permissions, part of CompTIA A+ (220-902) Cert Prep: 4 Virtualization Printers and Troubleshooting.
- If you're gonna have a modern operating system today,…you're gonna have to have file and folder permissions.…And certainly, Linux is no exception to that rule.…So in this episode, what I wanna do is go through Linux…file and folder permissions and then show you…how we can edit those.…So the best way to get started with this is to dive in,…go into a particular folder and just type ls -l.…So if you take a look here, on the far left-hand side…we see all these letters and dashes,…and that's really where all the file permission magic…takes place.…
As you look at this, on the far left-hand side,…you're gonna see one that has the letter d.…That means it's a directory.…So that very first value, I want you to just ignore it…for this episode.…That's just used to separate files from directories,…from links and other stuff like that.…What's important are the next nine values.…So if you take a look here, you're gonna see…individual files have r's and w's and x's and dashes…in different places, depending on what's happening here.…
Here CompTIA expert Mike Meyers prepares you to answer questions about slightly more advanced topics: "super tech" skills like managing files via the command-line interface, creating virtual machines, connecting to the Internet, installing printers, and troubleshooting startup and application issues. Each lesson prepares you for a related topic on the 90-question A+ exam.
