Script pour installer une AppImage


Recommended Posts

Bonjour
Les AppImage on l'avantage de s'exécuter facilement et l’inconvénient de ne pas s'installer.
pourtant le packaging inclus (parfois) un fichier desktop

voici un script pour installer une telle application 

placer le fichier appimage_install.sh dans votre dossier ${HOME}/.local/bin/ avec le droit "execute" pour le user

téléchargé une application AppImage (avec un fichier desktop inclus)
https://s3.mongobooster.com/download/releasesv7/nosqlbooster4mongo-7.0.3.AppImage

 

> appimage_install ~/download/nosqlbooster4mongo-7.0.3.AppImage
Installing nosqlbooster4mongo-7.0.3
extract desktop file
squashfs-root/nosqlbooster4mongo.desktop
extract icon file
squashfs-root/nosqlbooster4mongo.png
squashfs-root/usr/share/icons/hicolor/512x512/apps/nosqlbooster4mongo.png
copy nosqlbooster4mongo-7.0.3 to /home/jeanyves/.local/share/nosqlbooster4mongo-7.0.3
nosqlbooster4mongo-7.0.3: NoSQLBooster for MongoDB installed
