No no no.
Just pass m.e. a filename. Nothing else!
That %f or %F, %U or whatever is just options
in those *.desktop files if you like to edit them
manually.

command %f = program opens single files, even if
             multiple files are selected.

command %F = Use for apps that can open several
             local files at once.

try: mimeedit.sh -help

If you want to change def. app for some file,
pass it the filename.

If you want to add a mimetype to an existing app,
start it without any arguments.

Then pass it a file name of an existing jpg file.
Not, eog, gqview.desktop or similar...

Have a look at your:
/usr/share/mime/aliases

Have a look at your:
/usr/share/mime/subclasses
and your global mimeinfo.cache

Thanks, i will have a look.

Good point.

Both the "app list" and the app list for a mimetype
is sorted here. It is sorted by "sort -u" (line 74 and
line 322 in the script).

Here is the bug. The "FALSE" part is not ment to be
shown. That is only ment to tell zenity which radiobutton
that should be checked. False = unchecked True the opposite.

This tells me that the script builds a list that zenity
do not understand correctly. I will look into this using
your files.

But that should not be a problem if you start fresh and
let the script build your applications dir.

Probably the above.

Yes.

Here comes brick, catch!

Delete the ~.local/share/applications dir, no need
to restat anything.
Run the script with a *.mp3 filename.
Chose your desired app from the list.
Done, now it should open with the chosen app.

That is how it works here.

The selector choses the user version if there exists
both a global and a user .*desktop file containting
the same Exec=command

Could it be that "feature"?

> And what about the subdirectory /usr/share/applications/kde ? 

No idea.

> There's a lot of stuff stuff in: 

I wonder how you could get that many files in your
home dir. It should only contain changes from the
global, since there is no need to have anything
usercreated if the global works.

> Magnus, i don't like to shock you even more, but i feel obliged to mention that there seems to exist yet another system in /usr/share/application-registry. 

Yea, it is a mess. I know.

I do not have that folder.
$tree .
.
`-- share
    `-- applications
        |-- defaults.list
        |-- display-usercreated.desktop
        |-- gedit-usercreated.desktop

> I would really like to know how to start the 'selector' from gcmd via Settings-Edit mimetypes. And i like to know a more efficient way to test m.e. - do i always have to restart gcmd, or restart the session ? 

No. Any changes to mimeinfo.cache takes directly.

Settings-Edit mimetypes..
GCMD calls "gnome-file-types-properties"
And if you have a file named so in yor path it
will try to execute it.
