using xcopy to capture key input, how to exit the loop?

[Cornbeetle]

This is a short script I made to output user input to a text file using the xcopy method shared on dostips. After the user is finished typing, what can be done to exit the loop and "goto" a "finished" section?

Code: Select all

:start
set "key="
for /f "delims=" %%G in ('xcopy /W "%~F0" "%~F0" 2^>NUL') do if not defined key set "key=%%G"
set test=%key:~-1%
if "%test%"==" " (
   set /p x=,<nul >>output_keys.txt
   goto:start
) else (
   set /p =%key:~-1%<nul >>output_keys.txt
   goto:start
)

:finished

Seems you try to reinvent the wheel

To answer your question ...

Code: Select all

set test=%key:~-1%
if not defined test goto finished

As soon as Enter was pressed the captured character is a "Carriage Return" that will be declined in the next place.

I didn't think of the "carriage return" character, thanks! Works perfectly.
