This is version 2.0 of uefivars, a Linux user-space utility  to display the 
United Extensible Firmware Interface (UEFI) globally defined variables 
known to the kernel. You must be root to run this utility. 

The UEFI Specification is available from http://www.uefi.org.  See  
Table 10 of the UEFI specification Version 2.3.1C for a full list of 
the globally defined variables.
 
Note: this version of uefivars requires that the kernel was booted using UEFI
and the efivarfs filesystem is mounted.


Typical usage:
