-.TH BLKDISCARD 8 "September 2012" "util-linux" "System Administration"
-.SH NAME
-blkdiscard \- discard sectors on a device
-.SH SYNOPSIS
-.B blkdiscard
-.RB [ \-o
-.IR offset ]
-.RB [ \-l
-.IR length ]
-.RB [ \-s ]
-.RB [ \-v ]
-.I device
-
-.SH DESCRIPTION
-.B blkdiscard
-is used to discard device sectors. This is useful for solid-state
-drivers (SSDs) and thinly-provisioned storage. Unlike
-.BR fstrim (8)
-this command is used directly on the block device.
-.PP
-By default,
-.B blkdiscard
-will discard all blocks on the device. Options may be used to
-modify this behavior based on range or size, as explained below.
-.PP
-The
-.I device
-argument is the pathname of the block device.
-
-.B WARNING: All data in the discarded region on the device will be lost!
-
-.SH OPTIONS
-The \fIoffset\fR and \fIlength\fR arguments may be
-followed by the multiplicative suffixes KiB=1024, MiB=1024*1024, and so on for
-GiB, TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g. "K" has the same
-meaning as "KiB") or the suffixes KB=1000, MB=1000*1000, and so on for GB, PB,
-EB, ZB and YB.
-.IP "\fB\-h, \-\-help\fP"
-Print help and exit.
-.IP "\fB\-o, \-\-offset\fP \fIoffset\fP"
-Byte offset in the device from which to discard. Provided value will be
-aligned to the device sector size. Default value is zero.
-.IP "\fB\-l, \-\-length\fP \fIlength\fP"
-Number of bytes after starting point to discard. Provided value will be
-aligned to the device sector size. If the specified value extends past the
-end of the device,
-.B blkdiscard
-will stop at the device size boundary. Default value extends to the end
-of the device.
-.IP "\fB\-s, \-\-secure\fP"
-Perform secure discard. Secure discard is the same as regular discard except
-all copies of the discarded blocks possibly created by garbage collection must
-also be erased. It has to be supported by the device.
-.IP "\fB\-v, \-\-verbose\fP"
-Print aligned \fIoffset\fR and \fIlength\fR arguments.
