Is swap a partition, yet not a document system?

The common means to set up a swap room is indeed to usage a partition (like her /dev/sda2). The swap an are has some identifiers, so it can be determined as such, yet it"s no a file system: it doesn"t save files.

You could of course additionally put swap an are on a record on some regular filesystem.

(I wouldn"t speak swap is a partition, yet in deserve to lie on a partition.)

Is that the factor why df doesn"t present it?

That, and also the reality that df just shows mounted filesystems (visible come the process).

Is over there a command which can list every the partitions (whether castle hold file systems or not)?

All disc partitioning tools; fdisk, sfdisk, GParted, what have actually you. They can or could not show what"s within the partitions though.(/proc/partitions likewise contains a list, but not lot details.)
