A 90-byte “whereis” program – The Old New Thing
Posted by jpluimers on 2018/11/23
I needed a “get only the first result” of WHERE (which is present after Windows 2000, so XP, Server 2003 and up), so based on [WayBack] A 90-byte “whereis” program – The Old New Thing I came up with this:
@echo off
:: based on https://blogs.msdn.microsoft.com/oldnewthing/20050120-00/?p=36653
::for %%f in (%1) do @echo.%%~$PATH:f
for %%e in (%PATHEXT%) do @for %%i in (%1 %~n1%%e) do (
@if NOT "%%~$PATH:i"=="" (
echo %%~$PATH:i
goto :eof
)
)
:: note: WHERE lists all occurrences of a file on the PATH in PATH order
goto :eof
Two changes:
- it takes into account the extension if you specify it (unlike WHERE.EXE)
- it bails out at the first match (like WHERE.EXE)
