[SOLVED] A message "This text file seems to be an executable script" when opening FB2 files

Sam_Rosewood · 04-15-2017, 05:05 PM

Hello!
When opening FB2 files, the message "This text file seems to be an executable script. What do you want to do with it?" appears instead of opening by FB2Reader. Screenshot is attached.
How to remove this message and make these files to be opened by FB2Reader at once?
Lubuntu 16.04 x64.

Check your file association and make sure the file extension is linked to your FB2Reader.

And how to change it? I've added:
- "application/x-fictionbook+xml=FBReader.desktop" to /etc/gnome/defaults.list;
- "application/x-fictionbook+xml fb2 fb2.zip" to /etc/mime.types;
- "application/x-fictionbook+xml; /usr/bin/FBReader %s; test=test -n "$DISPLAY"" to /etc/mailcap;
and made reboot. There is no result.

Try turning off execute permission: chmod -x 1.fb2

Yes, it worked, but is it possible to fix it fo all FB2 files? It's not good to do this for all of the books in library.
Text files in another formats are opened correctly.

right-click the icon in your file manager, go properties => open with...
and set desired app as default.
works on pcmanfm.

As ondoho said should do the trick.

It doesn't help, even after rebooting.
PCManFM option "Don't ask option to launch executable file" doesn't help too. Nothing happens because system tries to launch it as executable, not to open it with FBReader.
As smallpond said, block executing work, but it has to be made for all books, and it's not comfortable at all.
Are there any ways to fix it once and forever? As you can see, I tried to do everything.

In your home directory there should be something like
.local/share/applications/mimeapps.list
or
.local/share/applications/defaults.list
which you can edit. Try adding something like
text/fb2=fbreader.desktop

it is possible that you downloaded a bunch of documents that some 1D10T marked executable.
that is annoying, but the only option is to change them back to NOT executable.

however:

that's strange, it surely works on my system.

you could show us where you got the files, or one of them, somebody could give it a try.

Sam_Rosewood · 04-16-2017, 07:51 PM

DavidMcCann, it doesn't help. System already has the type application/x-fictionbook+xml.
ondoho, I can't put this file here or link because of LQ rules. But I have a library of FB2 books, and this behaviour is for all of them. So I have a doubt that's the problem in files.
I can't understand logic of this extension system: pictures are opening in viewer, music and video - in player, documents - in LibreOffice. And it's correct. But these simple FB2 books show this annoying message.

I think the answer is going to be replacing PCManFM. On most file managers, you can set the default application for file types. Xfce is not that much bigger than LXDE, but Thunar has that facility.

ondoho · 04-17-2017, 01:09 PM

i'm using pcmanfm right now & have been for a long time and cannot, in a general way, reproduce the problem.
the preference dialog "Don't ask option to launch executable file" is effective.

now i think about it, pcmanfm runs as a daemon on Lubuntu, maybe it needs to be restarted for certain changes to take effect? Sam_Rosewood, have you tried to log out/in after changing the preferences?

Sam_Rosewood · 04-17-2017, 09:06 PM

DavidMcCann, this is not the way. I want to solve this problem, but not to go away from it.
ondoho, reboot doesn't help. This option "Don't ask option to launch executable file" works only if I set chmod -x in terminal or manually (screenshot). Yeah, I can set it for all the files in my library, but this is temporary measure. And I'll have to to it with every new FB2 file that I get. This is not comfortable.

You need to change the way the files are being saved. Not sure why the executable flag is being set on your downloads but that seems to be the problem.
