.SH "NAME"
nvme-config-show \- Show the resolved NVMe\-oF INI connection configuration
.SH "SYNOPSIS"
.sp
.nf
\fInvme\fR [<global\-options>] \fIconfig show\fR
                        [\-\-config=<file> | \-J <file>]
.fi
.SH "DESCRIPTION"
.sp
Reads the NVMe\-oF INI connection configuration file used by \fInvme connect\-all\fR and \fInvme discover\fR, and prints every configured connection entry\&. The INI format is documented at \m[blue]\fBhttps://github\&.com/linux\-nvme/nvme\-cli/blob/master/libnvme/design/CONFIG\&.md\fR\m[]
.sp
By default, the file at /etc/nvme/nvme\-fabrics\&.conf is read\&. Use \-\-config to show a file at a different path instead\&.
.sp
In the default and \fItabular\fR output formats, each entry is rendered as the equivalent command line that would establish it: \fInvme connect\-all\fR for a Discovery Controller entry, \fInvme connect\fR for an I/O Controller entry, preceded by a comment naming the entry\(cqs source (which file/section it came from)\&. The \fIjson\fR output format instead reports each entry\(cqs fields individually (transport, address, NQN, host identity, and any extra connect parameters)\&.
.sp
This command never touches the network: addressing is shown exactly as configured, with no hostname resolution attempted\&. A persona with no \fIhostnqn\fR/\fIhostid\fR set is shown without those fields rather than the system default it would resolve to at connect time, since showing a concrete value here would suggest a fixed identity the configuration doesn\(cqt actually pin\&.
.SH "OPTIONS"
.PP
\-J <file>, \-\-config=<file>
.RS 4
Show this INI file instead of the default /etc/nvme/nvme\-fabrics\&.conf\&.
.RE
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
