execute WshShell command from a batch script

Question

I\'ve got a simple question:

What\'s the best way to execute a single WshShell command from a Windows batch (.bat) script?

(hopefully it\'s not creating

Answer 1

This is the method I use to write a Batch-JScript hybrid script:

@if (@CodeSection == @Batch) @then

:: The first line above is...
:: in Batch: a valid IF command that does nothing.
:: in JScript: a conditional compilation IF statement that is false,
::             so this section is omitted until next "at-sign end".


@echo off

rem EXPR.BAT: Evaluate a JScript (arithmetic) expression
rem Antonio Perez Ayala

rem Define an auxiliary variable to call JScript
set JSCall=Cscript //nologo //E:JScript "%~F0"

rem Do Batch business here, for example:
%JSCall% %1
goto :EOF

End of Batch section


@end


// JScript section

WScript.Echo(eval(WScript.Arguments.Unnamed.Item(0)));

For example:

EXPR 1/3

EDIT: If you want a simpler/shorter method, use this one:

@set @a=0  /*
@cscript //nologo //E:JScript "%~F0" "%~1"
@goto :EOF */

WScript.Echo(eval(WScript.Arguments(0)));

Again, the first @set @a=0 /* is a valid statement/command in both JScript and Batch that is only used to insert the start of a JScript comment (/*), so the Batch section be ignored by JScript. The comment is closed (*/) after the final goto :EOF.
