'chmod -x install-sh' is not portable. -x looks like an option, but POSIX does not specify what an implementation must do with an option. And even if it is treated the same as 'chmod -- -x install-sh', which is specified by POSIX, it can only change mode bits according the the current setting of umask, such that the file might STILL be executable afterwards. It is much more portable to do 'chmod a-x install-sh'. -- Eric Blake
