How do I get information about a partition through the command line?

Question

On Ubuntu, I have the link to the partition (e.g. /dev/sda1). I want to know the labels, size,... of that partition.

How can I do that with a command in which the partition's link is a parameter? It is important to use this link in that command.

What about other devices?

Answer 1

df -h
fdisk -l

Will both give you different amounts of information on your mounted partitions.

Fdisk will give you more "physical" information like the heads and cylinder count. df will give you size information only.

Answer 2

fdisk -lu

in terms of sectors instead of cylinders.

See the man page for fdisk with the command:

man fdisk

Answer 3

dumpe2fs will give you that information if it's an E2FS partition (probably works with ext3 too)
