Question

You can set Unix permissions for some files or directories using changePermissions action. You will have to include a section like the one below inside an action list section of your XML installer project file.

       <changePermissions>
          <files>*/*.sh;*/*.bin</files>
          <permissions>755</permissions>
       </changePermissions>

The permissions are expressed in octal format. Please see the chmod manual page for details on how permissions work in Unix. By default, when building an installer on a Unix platform, the installer will preserve the permissions of the files being packed, so the above will not be necessary in most cases.
