Batch File Variables
Declaration
Variables are declared with the set [[Batch/BuiltinCommands#Set|builtin.
set foo=bar
Usage
Variables are accessed by their name. A percent sign (%) must surround the name.
set bar=%foo%
If a variable's value includes a character that the shell will interpret specially, quote the variable.
set bar="%foo%"
If a variable is not set, no substitution occurs.
set MyVar= echo %MyVar% # '%MyVar%'
Special Variables
Variable |
Value |
%# |
number of arguments |
%$ |
all arguments as a string |
%* |
all arguments as a string, unmodified by the shift builtin |
%@ |
all arguments as a string, but each token is quoted |
Positional Variables
The name of a command is stored in %0.
The first argument to the command is stored in %1. And so on until the 9th argument, %9.
For additional arguments, use the shift builtin to move them into the 9 accessible variables.
To get all arguments as a string (like %$) starting from index n, try %n$. To get all arguments until index n (non-inclusive), try %-n$.
