How do I check my filesystem disk usage?

To find out the available and used disk space, use df (disk filesystems, sometimes called disk free). To discover what’s taking up the used disk space, use du (disk usage). Type df and press enter in a Bash terminal window to get started. You’ll see a lot of output similar to the screenshot below.

How to determine the filesystem of an unmounted device?

Another command that can come handy is # file -sL /dev/sdXY. This has one downside in that it does not work with the full block device. Requires the exact device to be passed. The output is quite neat though: All of these will always be output to stdout.

How to find the size of an unmounted partition on Linux?

It doesn’t check anything, only says what is in the partition table. It doesn’t even bother if the partition table is damaged, or the block device doesn’t have one: it will print a warning that the checksum is not okay, but it still prints what is finds, even if the values are clearly non-sense.

How to show the filesystem type via the terminal?
