Most shell scripts are made to be invoked from a shell with certain parameters. Invoking them directly from a graphical application like Konqueror makes no sense or can even be harmful:
no output is displayed and no parameters can be specified. Instead of this they should be opened with an editor or viewed embeddedly.
  A 'run executables directly' switch could be disabled to edit shell scripts by default or to modify the startup modality of certain file types (e.g. start with parameters, as a terminal, without startup notification, etc.).
  Alternatively an 'apply to executables only' switch for each application program to open files of the given type could provide a richer set of functionality. If this switch is enabled for any of the listed application programs then executables are not started directly by default but with the given application entry.
