System Configuration
Arguments
Some commands require additional arguments to further define their action. For example, to
display information about the system memory, you must enter the command name, plus the
desired category of information to display:
fs0:\> info mem
Rules
Follow these rules to ensure the commands run correctly.
# Denotes a comment. All text from the # symbol to the end of the line is
ignored.
> Denotes an output redirect. Output of EFI shell commands can be saved to
files instead of being displayed on the monitor or in the terminal emulation
program. The shell redirects standard output to a single file and standard error
to a single file. Redirecting both standard output and standard error to the
same file is allowed. Redirecting to more than one file on the same command
is not supported.
The output redirect options, include:
> redirect output to a unicode file
>a redirect output to an ASCII file
>> append output to a unicode file
>>a append output to an ASCII file
The syntax for redirecting script output is:
Command > output_file_pathname
%
Denotes an environment variable. Environment variables can be set and
viewed through the use of the
set command (see set command in this
chapter). To access the value of an environment variable as an argument to a
shell command, delimit the name of the variable with the
% character before
and after the variable name; for example,
%myvariable%.
* Denotes a wildcard character. Matches zero or more characters in a file name.
? Denotes a wildcard character. Matches exactly one character of a file name.
[ Denotes a wildcard character. Defines a set of characters; the pattern matches
any single character in the set. Characters in the set are not separated. Ranges
of characters can be specified by specifying the first character in a range, then
the
- character, then the last character in the range. For example: [a-zA-Z].
^
Denotes a literal argument. When a command contains a defined alias the shell
replaces the alias with its definition (see
alias command in this chapter). If
the argument is prefixed with the
^ character, however, the argument is treated
as a literal argument and alias processing is not performed.
“” Quotation marks in the EFI shell are used for argument grouping. A quoted
string is treated as a single argument to a command, and any white space
characters included in the quoted string are just part of that single argument.
Quoting an environment variable does not have any effect on the
