Assume, for the sake of argument, that hw.c contains some C code. admin AT ubik /tmp/exemagic $ gcc hw.c -o hello.x admin AT ubik /tmp/exemagic $ ls -la total 125 drwxr-xr-x 1 DKAdmin None 0 May 24 20:36 . drwxrwxrwt 1 DKAdmin None 90112 May 24 20:36 .. -rwxr-xr-x 1 DKAdmin None 34326 May 24 20:36 hello.x -rw-r--r-- 1 DKAdmin None 121 May 24 20:36 hw.c admin AT ubik /tmp/exemagic $ ./hello.x Hello, .exe magic! admin AT ubik /tmp/exemagic $ mv hello.x hello.test.x admin AT ubik /tmp/exemagic $ ls -la total 125 drwxr-xr-x 1 DKAdmin None 0 May 24 20:36 . drwxrwxrwt 1 DKAdmin None 90112 May 24 20:36 .. -rwxr-xr-x 1 DKAdmin None 34326 May 24 20:36 hello.test.x.exe -rw-r--r-- 1 DKAdmin None 121 May 24 20:36 hw.c I expect this is probably one of those things that there's no way to avoid without breaking some far more common usage, perhaps? It's not that bad since it still runs as expected, and you can rename it again explicitly to get the name you really wanted: $ ./hello.test.x Hello, .exe magic! admin AT ubik /tmp/exemagic $ ls hello.test.x.exe hw.c admin AT ubik /tmp/exemagic $ mv hello.test.x.exe hello.test.x admin AT ubik /tmp/exemagic $ ls hello.test.x hw.c ... but I found it a bit surprising. Is it supposed to happen like this? I had a look in the recent announcement posts, and in /usr/share/doc, and couldn't find much explicit documentation about how exe magic works, but I noted that mv doesn't support `--disable-exe-magic'. cheers, DaveK -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
