-Sends one or more SCSI VERIFY commands to the given SCSI device.
-It is a 10 byte VERIFY command defined for block devices (see SBC-2
-at http://www.t10.org). Verify starts at the logical block address
-given by the '--lba=<n>' option and continues for '--count=<n>'
-blocks. No more than '--bpc=<n>' blocks are verified by each VERIFY
-command so if necessary multiple VERIFY commands are sent.
-No news is good news (i.e. if there are no verify errors detected
-no messages are sent to stderr and the Unix return status is 0).
+Sends one or more SCSI VERIFY commands to \fIDEVICE\fR. It is the 10 byte
+VERIFY command defined for block devices (see SBC\-2 at http://www.t10.org).
+Verify starts at the logical block address given by the \fI\-\-lba=LBA\fR
+option and continues for \fI\-\-count=COUNT\fR blocks. No more than
+\fI\-\-bpc=BPC\fR blocks are verified by each VERIFY command so if necessary
+multiple VERIFY commands are sent. No news is good news (i.e. if there are

+.SH OPTIONS
+Arguments to long options are mandatory for short options as well.
 .TP
---bpc=<n> | -b <n>
-specifies the maximum number of blocks that will be verified by a
-single SCSI VERIFY command. The default value is 128 blocks which
-equates to 64 KB for a disk with 512 byte blocks. If the value <n>
-is less than the value given to --count then multiple SCSI VERIFY
-commands are sent to the device. For recent block devices (disks)
-this value may be constrained by the maximum transfer length field
-in the block limits VPD page.
+\fB\-b\fR, \fB\-\-bpc\fR=\fIBPC\fR
+where \fIBPC\fR specifies the maximum number of blocks that will be verified
+by a single SCSI VERIFY command. The default value is 128 blocks which
+equates to 64 KB for a disk with 512 byte blocks. If \fIBPC\fR is less than
+\fICOUNT\fR then multiple SCSI VERIFY commands are sent to the device. For
+recent block devices (disks) this value may be constrained by the maximum
+transfer length field in the block limits VPD page.

---dpo | -d
-disable page out changes the cache retention priority of blocks read on
-the device's cache to the lowest priority. This means that blocks read by
-other commands are more likely to remain in the device's cache.

---count=<n> | -c <n>
-specifies the number of blocks to verify. The default value is 1 .
-If <n> is greater than the value associated with '--bpc' (or its default
-value of 128) then multiple SCSI VERIFY commands are sent to the
-device. The
+\fB\-c\fR, \fB\-\-count\fR=\fICOUNT\fR
+where \fICOUNT\fR specifies the number of blocks to verify. The default value
+is 1 . If \fICOUNT\fR is greater than \fIBPC\fR (or its default value of 128)
+then multiple SCSI VERIFY commands are sent to the device. The
 .B sg_readcap
 utility can be used to find the maximum number of blocks that a block
 device (e.g. a disk) has.

---lba=<n> | -l <n>
-specifies the logical block address on the device to start the verify
-operation. <n> is assumed to be decimal unless prefixed by '0x' or
-a trailing 'h' (see below). The default value is 0 (i.e. the start of the
-device).
+\fB\-l\fR, \fB\-\-lba\fR=\fILBA\fR
+where \fILBA\fR specifies the logical block address of the first block to
+start the verify operation. \fILBA\fR is assumed to be decimal unless prefixed
+by '0x' or a trailing 'h' (see below). The default value is 0 (i.e. the start
+of the device).

 increase the level of verbosity, (i.e. debug output).

 print the version string and then exit.
