or if no
.I block_device
was specified, from
.BR /dev/hda .
.I block_device
must be a non-partitioned, MBR-capable block device name, such as
.B /dev/hda
or
.BR /dev/hdb ,
etc.
.PP
If the
.B -l
option is not specified,
.B fdisk
will enter interactive mode and allow the user to manipulate the partition
