This is 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 Section 
3.2 Table 8 of the UEFI specification for a full list of the globally 
defined variables.
 
The EFI Specification is available from http://developer.intel.com.

Note: uefivars requires that the kernel was booted using UEFI


Typical usage:
