It needs to be readable as well. What ends up happening is that the kernel sees the execute bit, looks at the shebang line and then does: /bin/sh test Since read permission is off, the shell's open() call fails. It will work fine if you use 755 as the permissions. Every Unix I've ever seen works this way. It'd be nice to have unreadable executable scripts, but no one's ever done it. -Doug - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
