tss2_nvwrite1

Usage

Overview

tss2_nvwrite(1) - This command writes data to a “regular” (not pin, extend or counter) NV index. Only the full index can be written, partial writes are not allowed. If the provided data is smaller than the NV index’s size, then it is padded up with zero bytes at the end.

Options

These are the available options:

•

-i, --data=FILENAME or - (for stdin):

The data to write to the NV space.

•

-p, --nvPath=STRING:

Identifies the NV space to write to.

Options

This collection of options are common to all tss2 programs and provide information that many users may expect.

•

-h, --help [man|no-man]: Display the tools manpage. By default, it attempts to invoke the manpager for the tool, however, on failure will output a short tool summary. This is the same behavior if the “man” option argument is specified, however if explicit “man” is requested, the tool will provide errors from man on stderr. If the “no-man” option if specified, or the manpager fails, the short options will be output to stdout.

To successfully use the manpages feature requires the manpages to be installed or on MANPATH, See man(1) for more details.

•

-v, --version: Display version information for this tool, supported tctis and exit.

Examples

tss2_nvwrite --nvPath=/nv/Owner/myNV --data=data.file

Returns

0 on success or 1 on failure.
