To identify executable and other files in QT Application

[squidge]

Linux uses mime types instead of extensions, so you would get the mime type for your file and if it says "executable", then you would use QProcess to execute it/etc.

If you are unsure of the mime type used for a particular file, you can use the 'mimetype' command to figure it out. It's like 'file' but uses mime types instead of descriptions.

I use fedora, and it supports the file command, but not mimetype. I do have a high level of curiosity, however, so I poked around a bit.

I am stating what I believe to be true with hopes that you will correct me if I am incorrect.

• Gnome uses mime types to associate applications with files.
• Gnome mime types use magic numbers to recognize the mime type.
• There may be multiple associations for a specific type; for example, an OOo document may associate to an OOo document type and also to a ZIP file. This is, of course, as it should be.

I looked at the gnome mime-type stuff in the file /etc/gnome-vfs-mime-magic

Very interesting...
