kill sends a specified signal to the specified process.
more is a filter for paging through text one screen full at a time.
mount mounts a filesystem from a device to a directory (mount point).
umount unmounts a mounted filesystem.
agetty opens a tty port, prompts for a login name and invokes the /bin/login command.
blockdev allows to call block device ioctls from the command line
cfdisk is an libncurses based disk partition table manipulator.
ctrlaltdel sets the function of the CTRL+ALT+DEL key combination (hard or soft reset).
elvtune allows to tune the I/O elevator per block device queue basis.
fdisk is a disk partition table manipulator.
fsck.minix performs a consistency check for the Linux MINIX filesystem.
hwclock queries and sets the hardware clock (Also called the RTC or BIOS clock).
