How to get File version in variable using .cmd

问题

I used wmic to get the version of a EXE stored in a variable. It works fine when I execute it from CMD (that I ran as Admin) but when executed either in a .cmd or .bat files (even when ran as admin) the variable is not populated.

This works directly in CMD:

set "npver="&for /F "tokens=2delims==" %a in ('wmic datafile where "Name='c:\\Windows\\System32\\notepad.exe'" get version /format:list') do set "npver=%a"

When I created the .cmd file, I doubled the % signs.

回答1:

You forgot to echo the variable with the command echo %npver%

With Command line :

set "npver="&for /F "tokens=2delims==" %a in ('wmic datafile where "Name='c:\\Windows\\System32\\notepad.exe'" get version /format:list') do set "npver=%a"& echo %npver%

With a batch file, you should escape the sign percent % by adding another one %% and your code should works now with a batch file like this :

Batch File :

@echo off
set "npver="&for /F "tokens=2delims==" %%a in ('wmic datafile where "Name='c:\\Windows\\System32\\notepad.exe'" get version /format:list') do set "npver=%%a"
echo %npver%
pause

EDIT : Get_File_Version.bat

Here is another code in batch more elaborated to get file version of any Application from file list using WMIC.

@echo off
