I can't ever get a non-0 with this idiom on the CMD command line. (Haven't tried in a batch file now, but would be (kinda-sorta, "historic'ly") interesting to find out what the hell...)
This form still works (in the same context), though: nmake /f nonexisting || if errorlevel 1 echo FAILED!
Still can't capture & forward the original exit code of the failed process.
But at least this form also works with if: if something nmake /f nonexisting || if errorlevel 1 echo FAILED!
FWIW (also -> #21!):
nmake /f nonexisting || echo %ERRORLEVEL%-> 0dir nonexisting || echo %ERRORLEVEL%-> 0nonexisting || echo %ERRORLEVEL%-> 0...I can't ever get a non-0 with this idiom on the CMD command line.
