.
.TP
.B \-f

.SH EXAMPLE
.\" ----------------------------------------------------------------------------
.
To mount all the partitions in a raw disk image:
.IP
kpartx \-av disk.img
.PP
This will output lines such as:
.IP
add map loop1p1 (254:4): 0 409597 linear 7:1 3
.PP
The \fIloop1p1\fR is the name of a device file under \fI/dev/mapper\fR which you
can use to access the partition, for example to fsck it:
.IP
fsck /dev/mapper/loop1p1
.PP
When you're done, you need to remove the devices:
.IP
kpartx \-d disk.img
.
