Overview
Use mimetype to view the MIME type of a file
mimetype myfile.svg
# myfile.svg: image/svg+xml
Using see
To change default application used by see for a given MIME type:
- For user, edit ~/.mailcap:
image/svg+xml; /usr/bin/chromium %s; test=test -n "$DISPLAY"
- System-wide, edit /etc/mailcap.order, then run
sudo update-mime:
evince:application/pdf
Other relevant information:
man mimetype
man mimeview
man mimeopen # Apparently not same as "see"
man see
Using xdg-open
xdg-open is used by desktop application, but also Midnight Commander (mc).
To query default application:
xdg-mime query filetype myfile.svg
# image/svg+xml
xdg-mime query default image/svg+xml
# eog.desktop
To change the default:
xdg-mime default chromium.desktop image/svg+xml
xdg-mime query default image/svg+xml
# chromium.desktop
Troubleshooting
Open PDF files with Evince (instead of Gimp)
On recent Debian / Ubuntu releases, PDF files are opened by Gimp instead of the PDF viewer, like Evince.
To fix the issue system-wide:
- Create a MIME entry for
evince[1]:
echo 'application/pdf; evince %s; test=test -n "$DISPLAY"' | sudo tee /usr/lib/mime/packages/evince
- Change MIME order in /etc/mailcap.order:
echo 'evince:application/pdf'| sudo tee -a /etc/mailcap.order
sudo update-mime
