You can achieve this by using the SET command in a Windows batch script. Here's how you can trim N characters from the end of a string:

batch
@echo off
setlocal

set "inputString=HelloWorld"
set "charsToTrim=5"

set "trimmedString=%inputString:~0,-%charsToTrim%%"

echo Trimmed string: %trimmedString%

endlocal

Replace HelloWorld with your actual string and 5 with the number of characters you want to trim from the end of the string. The ~ operator in the set "trimmedString=%inputString:~0,-%charsToTrim%" line is used to perform the substring operation.

When you run this script, it will output the trimmed string.

Keep in mind that this method works only for strings that don't contain special characters like exclamation marks (!) due to delayed variable expansion. If your strings contain special characters, you might need to enable delayed expansion or use other techniques to handle them.
