SET [-v] [sname [value]]
SET [-d
-d - Deletes the environment variable
-v - Volatile variable
sname - Environment variable name
value - Environment variable value
Notes:
1. SET values are stored in EFI NVRAM and will be retained between boots
unless the option -v is specified.
2. The dmpstore command can be used to display EFI Shell NVRAM variables.
3. Available NVRAM storage available for the set command will depend on
the system implementation.
4. SET may store NVRAM variables on the file system /efi/boot/bootstr.nvr
if no NVRAM is implemented by the core EFI routines.
Examples:
* To add an environment variable:
Shell> set DiagnosticPath fs0:\efi\diag;fs1:\efi\diag
* To display all environment variables:
Shell> set
* path : .
diagnosticPath : fs0:\efi1.1\diag;fs1:\efi1.1\diag
* To delete an environment variable:
Shell> set -d diagnosticpath
Shell> set
* path : .
* To change an environment variable:
fs0:\> set src efi
fs0:\> set
* path : .;fs0:\efi\tools;fs0:\efi\boot;fs0:\
src : efi
fs0:\> set src efi1.1
fs0:\> set
* path : .;fs0:\efi\tools;fs0:\efi\boot;fs0:\
src : efi1.1
* To append an environment variable:
Shell> set
* path : .
Shell> set path %path%;fs0:\efi\tools;fs0:\efi\boot;fs0:\
Shell> set
* path : .;fs0:\efi\tools;fs0:\efi\boot;fs0:\
* To set a volatile variable that will disappear at the next boot:
Shell> set -v EFI_SOURCE c:\project\EFI1.1
Shell> set
* path : .;fs0:\efi\tools;fs0:\efi\boot;fs0:\
* EFI_SOURCE : c:\project\EFI1.1
