.SH "NAME"
nvme-changed-ns-list-log \- Send NVMe Changed Namespace List log page request, returns result and log\&.
.SH "SYNOPSIS"
.sp
.nf
\fInvme changed\-ns\-list\-log\fR <device> [\-\-raw\-binary | \-b]
                        [\-\-output\-format=<fmt> | \-o <fmt>]
.fi
.SH "DESCRIPTION"
.sp
Retrieves the NVMe Changed Namespace List log page from an NVMe device and provides the returned structure\&.
.sp
The <device> parameter is mandatory and must be a NVMe character device (ex: /dev/nvme0)\&.
.sp
On success, the returned Changed Namespace List log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
.SH "OPTIONS"
.PP
\-b, \-\-raw\-binary
.RS 4
Print the raw Changed Namespace List log buffer to stdout\&.
.RE
.PP
\-o <format>, \-\-output\-format=<format>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR, or
\fIbinary\fR\&. Only one output format can be used at a time\&.

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c

.el \{\
.sp -1
.IP \(bu 2.3
.\}
Print the Changed Namespace List Log page in a human readable format:
.sp
.if n \{\
.RS 4
.\}
.nf
# nvme changed\-ns\-list\-log /dev/nvme0
.fi
.if n \{\

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Print the raw Changed Namespace List log to a file:
.sp
.if n \{\
.RS 4
.\}
.nf
# nvme changed\-ns\-list\-log /dev/nvme0 \-\-raw\-binary > log\&.raw
.fi
.if n \{\
.RE

It is probably a bad idea to not redirect stdout when using this mode\&.
