In this video, we'll briefly talk about file systems.
The next lesson, lesson 6, is entirely dedicated to working with file systems, so you will
find more information in there.
But for now, the main thing is, once you finish creating a partition or any other block device,
you need to put a file system on top.
Because a partition is only a reservation of disk space.
And if you don't put a file system on top of it, there's nothing that you can do with
your partition.
Different file systems exist, but ext4 and xfs are most commonly used.
Xfs is what you typically find in Red Hat environments and in Ubuntu environments, you'll
find ext4.
You can use mkfs.xfs or mkfs.ext4 to create these file systems.
And both of these commands work with the option –l to give the file system a label.
And you can use mount to connect a file system to a directory as a mount point.
Again, all the gory details about working with file systems are covered in lesson 6,
so to be continued.
