The curious case of the missing exclamation mark in CMD files

Question

I have whittled down a more complex CMD script to the essentials. It reads an input file line by line, unquotes it (if quoted) and writes it out to another CMD file.

Answer 1

Like this :

@echo off

(for /f "delims=" %%a in ('type bang1.txt') do echo  echo P1:[%%~a])>bang2.cmd
