Join Sean Colins for an in-depth discussion in this video Copying files, part of Linux: Firewalls and SELinux.
- [Instructor] Copying and moving files…are obviously different things.…In this movie we'll talk about copying files…and how different operations will affect the results.…As systems administrators we have to…do things like this for our users frequently,…especially if we're file server admins.…That being said, just to be clear,…a copy operation is run by the cp process…and it takes a file and creates a duplicate…of that file somewhere.…While the move operation is performed by the mv command…and takes a file and makes a duplicate…of that file somewhere and then deletes the original file.…These are two very different results.…Here's how they work if you employ the dash Z flag…to bring SELinux into the process.…
