.SH "NAME"
nvme \- the NVMe storage command line interface utility (nvme\-cli)
.SH "SYNOPSIS"
.sp
built\-in plugin:
.sp
.nf
\fInvme\fR <command> <device> [<args>]
.fi
.sp

.SH "DESCRIPTION"
.sp
NVM\-Express is a fast, scalable host controller interface designed to address the needs for not only PCI Express based solid state drives, but also NVMe\-oF(over fabrics)\&.
.sp
This \fInvme\fR program is a user space utility to provide standards compliant tooling for NVM\-Express drives\&. It was made specifically for Linux as it relies on the IOCTLs defined by the mainline kernel driver\&.
.SH "NVME COMMANDS"
.sp
The utility has sub\-commands for all admin and io commands defined in the specification and for displaying controller registers\&. There is also an option to submit completely arbitrary commands\&. For a list of commands available, run "nvme help"\&.
