System Configuration
[ 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 whitespace
characters included in the quoted string are just part of that single argument.
Quoting an environment variable does not have any effect on the
de-referencing of that variable. Double quotation marks (
“ ” ) denote strings.
Single quotation marks are not treated specially by the shell in any way.
Empty strings are treated as valid command line arguments.
space
Used to format batch scripts to separate command names, parameters and so
forth.
newline
Used to format batch scripts. Each line represents a new command.
