# MIME
|
|
|
|
A MIME type (short for Multipurpose Internet Mail Extensions) is a identifier
|
|
for file formats and contents on the internet.
|
|
|
|
## Usage
|
|
|
|
### Setting applications for MIME types
|
|
|
|
In `~/.config/mimeapps.list` a list of applications to run specific MIME
|
|
types can be found.
|
|
An example file looks like the following:
|
|
|
|
```txt
|
|
[Default Applications]
|
|
text/x-shellscript=text.desktop;
|
|
x-scheme-handler/magnet=torrent.desktop;
|
|
application/x-bittorrent=torrent.desktop;
|
|
x-scheme-handler/mailto=mail.desktop;
|
|
text/plain=text.desktop;
|
|
application/postscript=pdf.desktop;
|
|
application/pdf=pdf.desktop;
|
|
image/png=img.desktop;
|
|
image/jpeg=img.desktop;
|
|
image/gif=img.desktop;
|
|
application/rss+xml=rss.desktop
|
|
video/x-matroska=video.desktop
|
|
inode/directory=file.desktop
|
|
```
|
|
|
|
A line consists of a MIME type left of the equals sign and an application on
|
|
the right of it.
|
|
The application can be found in `~/.local/share/applications/`.
|
|
In this directory a file for every application on the right side of the equals
|
|
sign with the same title can be found.
|
|
|
|
A simple application file looks like the following example of `img.desktop`:
|
|
|
|
```txt
|
|
[Desktop Entry]
|
|
Type=Application
|
|
Name=Image viewer
|
|
Exec=/usr/bin/sxiv -a %f
|
|
```
|
|
|
|
Atleast `Type`, `Name` and `Exec` have to be specified for a minimal
|
|
application file.
|
|
|
|
### Getting MIME type of a file
|
|
|
|
The MIME type of a file can be returned by running
|
|
`xdg-mime query filetype <file>` or `file -b --mime-type image.png`.
|
|
The MIME type can be then used to set default applications as explained in
|
|
[the section regarding setting applications for MIME types](#setting-applications-for-mime-types).
