ubuntu 设置默认值 VLC / LibreOffice 等

Associate all audio and video files to VLC instead of Totem media player (Movie Player)

 

Video files: .avi .mp4 .mpg .ogv .ogm .mkv .wmv etc.
Audo files: .mp3 .ogg .flac .wav .wma etc.

 

Open defaults.list with gedit:

gksudo gedit /usr/share/applications/defaults.list

 

And replace all occurences of totem with banshee/rythmbox/vlc or the media player of your choice.
(Search → Replace → Replace All)  (=totem.desktop => =vlc.desktop)

 

 

Save the modified file, and you're done! Change are effective immediately.

 

 

Associate all office documents to LibreOffice instead of OpenOffice.org or Abiword

 

Office files:  .odt  .ods.  .doc  .docx  .xls  .xlsx  etc.

 

Open defaults.list with gedit:

gksudo gedit /usr/share/applications/defaults.list

 

And replace all occurences of "openoffice.org" with "libreoffice".
(Search → Replace → Replace All)

 

Finally, save the file. No need to restart, you're all set!

 

Ubuntu's case

For an obscure reason, changing the file associations directly in the defaults.list doesn't seem to work Ubuntu 10.10 "Maverick Meerkat". Nevertheless, importing information to the the mimeapps.list works.

 

The file associations for each user are stored in:

~/.local/share/applications/mimeapps.list

 

In Ubuntu 10.10 "Maverick Meerkat" (and probably 10.04 "Lucid Lynx"), this file is almost empty. Let's import informations from

/usr/share/applications/defaults.list

 

Display all the video MIME types associations with this command:

cat /usr/share/applications/defaults.list | grep video

 

Append all the lines containing video types to the local file:

cat /usr/share/applications/defaults.list | grep video >> ~/.local/share/applications/mimeapps.list

 

Open defaults.list with gedit:

gedit ~/.local/share/applications/mimeapps.list

 

And replace all occurences of totem with vlc (Search → Replace...) Proceed similarly for audio files if needed.
