NAME

       efi-readvar - tool for showing secure variables

SYNOPSIS

       efi-readvar: [-v <var>] [-s <list>[-<entry>]] [-o <file>]

DESCRIPTION

       with no arguments, prints out the entire secure variable database and expands the contents
       of hashes and X509 certificates.  May be restricted to  specific  variables  and  specific
       signatures within variables.  Note that EFI signature lists are numbered from zero and may
       contain one or more entries (also numbered from zero), so 0-0 represents the  first  entry
       of signature list zero.

       List the contents of the UEFI signature databases
