COMMON OPTIONS

24       This collection of options are common to many programs and provide  in‐
25       formation that many users may expect.
26
27       • -h,  --help=[man|no-man]:  Display the tools manpage.  By default, it
28         attempts to invoke the manpager for the  tool,  however,  on  failure
29         will  output  a short tool summary.  This is the same behavior if the
30         “man” option argument is specified, however if explicit “man” is  re‐
31         quested,  the  tool  will  provide errors from man on stderr.  If the
32         “no-man” option if specified, or the manpager fails,  the  short  op‐
33         tions will be output to stdout.
34
35         To  successfully use the manpages feature requires the manpages to be
36         installed or on MANPATH, See man(1) for more details.
37
38       • -v, --version: Display version information for this  tool,  supported
39         tctis and exit.
40
41       • -V,  --verbose:  Increase the information that the tool prints to the
42         console during its execution.  When using this option  the  file  and
43         line number are printed.
44
45       • -Q, --quiet: Silence normal tool output to stdout.
46
47       • -Z, --enable-errata: Enable the application of errata fixups.  Useful
48         if an errata fixup needs to be applied to commands sent to  the  TPM.
49         Defining  the environment TPM2TOOLS_ENABLE_ERRATA is equivalent.  in‐
50         formation many users may expect.
