COMMON OPTIONS

This collection of options are common to many 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.

• -V, --verbose: Increase the information that the tool prints to the console during its
execution. When using this option the file and line number are printed.

• -Q, --quiet: Silence normal tool output to stdout.

• -Z, --enable-errata: Enable the application of errata fixups. Useful if an errata fixup
needs to be applied to commands sent to the TPM. Defining the environment
TPM2TOOLS_ENABLE_ERRATA is equivalent.

• -R, --autoflush: Enable autoflush for transient objects created by the command. If a
parent object is loaded from a context file also the transient parent object will be
flushed. Autoflush can also be activated if the environment variable
TPM2TOOLS_AUTOFLUSH is is set to yes or true. information many users may expect.
