copied!<p>You have multiple problems in your modified check.bat</p> <p>The quotes are a state machine in that the 1st quote turns quoting semantics ON, the 2nd OFF, the 3rd ON, etc. An unquoted (and unescaped) <code>></code> is interpreted as an instruction to redirect output.</p> <p>I've heavily modified check.bat by putting in a bunch of ECHO statements to provide a narrative of what is happening. Your original code is embedded in my version as all CAPS.</p> <p>Here is the output of my modified version, which I hope explains why you are getting your results. I want you to read this output before you try to understand how my modified check.bat produces this output.</p> <pre><code>"a" --------------------------------------------- Executing: SET RAWINPUT=%1 which expands to SET RAWINPUT="a" Here is the result: rawinput="a" Executing: SET INPUT=%~1 which expands to SET INPUT=a Here is the result: input=a Executing: ECHO %1 which expands to ECHO "a" "a" Executing: ECHO "%RAWINIPUT%" which expands to ECHO ""a"" ""a"" Executing: ECHO "%INPUT%" which expands to ECHO "a" "a" "b -> b" --------------------------------------------- Executing: SET RAWINPUT=%1 which expands to SET RAWINPUT="b -> b" Here is the result: rawinput="b -> b" Executing: SET INPUT=%~1 which expands to SET INPUT=b -> b Here is the result: input=b - Also created a file named "b" because the output of the command is redirected.

Within check.bat you can use delayed expansion to safely work with any value without worrying about quotes or escapes.</p>
