CHAPTER 12 EFI Shell and EFI Commands

 

Shell environment variables can be specified and referenced with the set command.

As shown below, the environment variable name must be enclosed between the % 
characters for access when it is used as an argument to a shell command:

%myvariable%

The shell has a special variable called lasterror.  This variable retains the return value 
of the shell command executed last.

The "*", "?", "[", and "]" characters are handled as wildcard characters in a file name 
used as an argument to a shell command.
