COMMON OPTIONS

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

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