Aliases can use command line parameters or parameters like those in batch files. The command line parameters are numbered from %0 to %511. (%0 contains the alias name.)
For example, the following alias will change directories, perform a command, and return to the original directory:
alias in
pushd %1 & %2$ & popd
when i run the above, my command prompt gives error saying
%1 * Unable to read value of alias * '%2' is not recognized as an internal or external command, operable program or batch file. 'popd`' is not recognized as an internal or external command, operable program or batch file.
if you use double quote instead, alias in "pushd %1 & dir & popd" it doesn't interprets the %1 when you execute the alias
C:\abc\def>alias Dumping all defined aliases for CMD.EXE. in =pushd %1 & dir & popd
alias def wont work
---------EDIT------------ let me try some sample output with a simple echo alias
D:\abc\def>alias /?
Usage: ALIAS [-v] [-p programName] [-f filespec] [ ]
[-v] means verbose output.
[-d] means delete aliases.
[-p programName] specifies which image file name these alias
definitions are for. Default is CMD.EXE
[-f filespec] specifies a file which contains the alises.
C:\Office\dev15>alias out 'echo %1'
%1' * Unable to read value of alias *
C:\Office\dev15>alias out backtick echo %1 backtick
%1` * Unable to read value of alias *
C:\Office\dev15>alias out "echo %1"
C:\Office\dev15>alias
Dumping all defined aliases for CMD.EXE.
out =echo %1
C:\Office\dev15>out abc
%1
C:\Office\dev15>alias out echo %1
%1 * Unable to read value of alias *
C:\Office\dev15>out abc
ECHO is on.
Problem is, both single quote and back tick produces error, while double quote wont treat %1 as variable parameter
