The command is mkfs. Though usually most people will use:
mkfs.<filesystem type> /dev/sdXY
Where X is the drive and Y is the partition.
For example: mkfs.ext4 /dev/sda3 means "Create an ext4 filesystem on the third partition of the first drive."
As files can be of any number of types, there is no single command that will do this. You would use the program associated with that file type to create a file. If you wanted to create a "blank" file, that has no content and uses no space, use the command touch filename.
mknodRun this command to see the documentation for it:man mknodIn current systems you don't have to make devices, because udev does it for you.

Anything can be made into a command on a Linux system. The steps are easy. First, using any text editor (vim, emacs, etc.) create a text file. Put anything you want to do in this file. Save the file. Make sure the file you just created has read and execute permissions (chmod). That's it! Now you have a command that you can execute in Linux.
There are programs you can download that will read Linux file systems. Common file systems are ext2 and ext3.
On most Linux distros, try this command:$ df -m The df command is popularly considered to stand for disk free, though I don't really know if this is fact or myth.Caveat: The above command will only display information on mounted file systems.
