37
38                - recnum: Unique record number
39                - pcr: PCR index
40                - digest: The digests
41                - type: The type of event. At the moment the only possible value is: "LINUX_IMA" (legacy IMA)

COMMON OPTIONS

46       This collection of options are common to all tss2 programs and  provide
47       information that many users may expect.
48
49       · -h,  --help  [man|no-man]: Display the tools manpage.  By default, it
50         attempts to invoke the manpager for the  tool,  however,  on  failure
51         will  output  a short tool summary.  This is the same behavior if the
52         “man” option argument is specified, however if explicit “man” is  re‐
53         quested,  the  tool  will  provide errors from man on stderr.  If the
54         “no-man” option if specified, or the manpager fails,  the  short  op‐
55         tions will be output to stdout.
56
57         To  successfully use the manpages feature requires the manpages to be
58         installed or on MANPATH, See man(1) for more details.
59
60       · -v, --version: Display version information for this  tool,  supported
61         tctis and exit.
