19
20       · -a, --authValue STRING:
21
22         The new UTF-8 password.  Optional parameter.  If it is neglected then
23         the  user  is  queried interactively for a password.  To set no pass‐
24         word, this option should be used with the empty string ("").

COMMON OPTIONS

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