The meaning of the options is as follows.</para> (default). </screen> +<para>Normally, files ending in certain extensions (.exe, .com, .bat, .btm, +.cmd) are assumed to be executable. Files whose first two characters begin +with '#!' are also considered to be executable. +The <literal>exec</literal> option is used to instruct Cygwin that the +mounted file is "executable". If the <literal>exec</literal> option is used +with a directory then all files in the directory are executable. +This option allows other files to be marked as executable and avoids the +overhead of opening each file to check for a '#!'. The +<literal>cygexec</literal> option is very similar to <literal>exec</literal>, +but also prevents Cygwin from setting up commands and environment variables +for a normal Windows program, adding another small performance gain. The +opposite of these options is the <literal>notexec</literal> option, which +means that no files should be marked as executable under that mount point. +</para> + <para>Note that nouser mount points are not overridable by a later call -to mount(2).
