10

DESCRIPTION

12       tss2_nvextend(1)  -  This command performs an extend operation on an NV
13       index (i.e. an NV index that behaves similar to a PCR).
14

OPTIONS

16       These are the available options:
17
18       · -i, --data FILENAME or - (for stdin):
19
20         The data to be extended into the NV space.
21
22       · -p, --nvPath STRING:
23
24         Identifies the NV space to write.
25
26       · -l, --logData FILENAME or - (for stdin):
27
28         A JSON representation of data to be written to the PCR’s  event  log.
29         Optional parameter.

COMMON OPTIONS

32       This  collection of options are common to all tss2 programs and provide
33       information that many users may expect.
34
35       · -h, --help [man|no-man]: Display the tools manpage.  By  default,  it
36         attempts  to  invoke  the  manpager for the tool, however, on failure
37         will output a short tool summary.  This is the same behavior  if  the
38         “man”  option argument is specified, however if explicit “man” is re‐
39         quested, the tool will provide errors from man  on  stderr.   If  the
40         “no-man”  option  if  specified, or the manpager fails, the short op‐
41         tions will be output to stdout.
42
43         To successfully use the manpages feature requires the manpages to  be
44         installed or on MANPATH, See man(1) for more details.
45
46       · -v,  --version:  Display version information for this tool, supported
47         tctis and exit.
