V, -version output version information and exitДЄs you can see, the -t flag lets us pass filesystem-specific flags. t, -type=TYPE file system type, when undefined ext2 is usedДЇs-options parameters to real file system builderДefining -V more than once will cause a dry-run The general syntax for mkfs is: # mkfs -help You'll use the block device corresponding to the partition you want to format, such as /dev/sda2. In fact, it expects block devices, so if I'm going to use a new file /tmp/file for mkfs, I have to force it do so. Now, unfortunately, while parted operates just fine on a file, like the one I used above, mkfs can't go hunting for partitions in such files. On my system for example, mkfs.bfs, mkfs.cramfs, mkfs.ext2, mkfs.ext3, mkfs.ext4, mkfs.ext4dev, mkfs.fat, mkfs.minix, mkfs.msdos, mkfs.ntfs, mkfs.vfat are available. Mkfs, like fsck, is essentially a frontend to various filesystem-specific commands.

Indeed, parted will tell you that you should use it for manipulating partitions, not filesystems, which brings me to: While parted can create partitions of filesystem ntfs just fine, it can't format an existing partition (!) to NTFS: mkfs partition fs-type I'll label the partitions: # parted /tmp/part name 1 hello Note how it uses SI prefixes, whereas GParted steadfastly uses binary prefixes (while dropping the silly i). Number Start End Size File system Name Flags Sector size (logical/physical): 512B/512B parted expects locations in MB for mkpartfs, but we can specify the suffix: parted /tmp/part mkpart primary ext4 3G 5GДЄnd another, now an NTFS partition of 1GB: parted /tmp/part mkpart primary ntfs 5G 6G

Then we make, say, an ext4 partition starting starting at 3GB (i.e., leaving the initial 3G free) and of size 2GB (i.e., ending at 5GB). Or mklabel msdos, if you want the old-school 4-primary-partition thing (called MBR or MSDOS partition table). You should replace that with the device you need ( /dev/sda, for example).ДЇirst, if your disk doesn't have a partition table, we must create one: parted /tmp/part mklabel gpt I'm going to use a temporary file ( /tmp/part) I created to show you the commands, so the sizes will be somewhat small. The commands can be contracted to a unique prefix (e.g., h is short for help).

Parted doesn't need an argument (it tries to 'guess'), but you should always specify the disk. It has the following commands: Command action The mkfs commands are not interactive.ДЇdisk expects a device (such as /dev/sda) as an argument.
