This used to align text to the right, which is normally used to improve readability of number columns.
@echo off set x = 1000 set y = 1 set y = %y% echo %x% set y = %y:~-4% echo %y%
A few key things to note about the above program is −
Spaces are added to the variable of y, in this case we are adding 9 spaces to the variable of y.
We are using the ~-4 option to say that we just want to show the last 4 characters of the string y.
The above command produces the following output. The key thing to note is that the value of 2 is aligned to match the units columns when displaying numbers.
