Remove Trailing Slash From Batch File Input

Question

I have a batch file that I want to improve. Instead of requiring a user to provide a folder path without a trailing slash, is there an easy way for me to just remove the last character from the path if there is a slash on the end?

:START @echo What folder do you want to process? (Provide a path without a closing backslash) set /p datapath=  ::Is string empty? IF X%datapath% == X GOTO:START  ::Does string have a trailing slash? IF %datapath:~-1%==\ GOTO:START 

Answer 1

you can use syntax similar your evaluation:

::Does string have a trailing slash? if so remove it  IF %datapath:~-1%==\ SET datapath=%datapath:~0,-1%
