Question

I need to create a batch file that reads a file with one line and then renames the same file based on the contents.
The file will have one number and the condition to rename the file is this:

If content of file > 100 then rename new.txt to old.txt
else rename new.txt to new1.txt

Thanks for the help!

Answer 1

@echo off
set /p line=<new.txt
if %line% GTR 100 (
  ren "new.txt" "old.txt"
)else (
  ren "new.txt "new1.txt"
)
