Put command output into a variable

Question

Given a directory with the following files

image1.txt
image2.txt
image3.txt

I want to get the oldest file (let the files be sorted by data, old

Answer 1

For /F %%A in ('"dir /b /od C:\test\image*.txt|findstr ^1"') do set myVar=%%A

You could do it through For loop, try that in command line, I just tested it and it works fine

Output:

set myVar=image1.txt

On executing Set on command line you can see:

myVar=image1.txt
NUMBER_OF_PROCESSORS=2
