batch script for windows setting variable value

Question

This part of script is not setting value for variable creationYear.

set creationYear=dir/T:C %%i | cut -c 7-10

echo %creationYear%

Showing ECHO is off, there is @ECHO OFF at start.

If this part of your batch code is inside a for loop or if condition, you need to use delayed environment variable expansion. Open a command prompt window, execute there set /? and read the help pages output now. On Stack Overflow search with [batch-file] delayed expansion and you will find thousands of questions and answers. — Mofi

And you can't assign output of a command to an environment variable with the method you tried here. You need a for loop for this task. To get help on command for, open a command prompt window, execute there for /? and read the help pages output now. Of course on Stack Overflow there are thousands of questions and answers demonstrating how to assign output of a command to an environment variable using for. — Mofi

for /f "tokens=* delims=" %%# in ('dir/T:C %%i ^| cut -c 7-10') do (
 set "creationYear=%%#" 
)
echo %creationYear%

despite you can get the creation date without external tools like cut
