       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.

tss2_pcrextend(1) - This command extends the data into the PCR listed.  The parameter logData is extended
       into the PCR log.  If the logData is NULL, only the PCR extend takes place.  All PCRs currently active in
       the TPM are extended.

       These are the available options:

       • -x, --pcr=INTEGER:

       The PCR to extend.

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

         The event data to be extended.

       • -l, --logData=FILENAME or - (for stdin):

         Contains a JSON representation of data to be written to the PCR’s event log.  Optional parameter.

       0 on success or 1 on failure.

fapi-config(5)  to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for
       the Fapi metadata storages.

       fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys and operations of a
       specific TPM interaction like the name hash algorithm, the asymmetric signature algorithm, scheme and pa‐
       rameters and PCR bank selection.
