How To Install And Use An AppImage

Step 1: Download the AppImage

Step 2: Make the AppImage Executable

After downloading the AppImage, it won’t be executable by default. You need to change its permissions to make it executable.

cd ~/Downloads
chmod +x Obsidian-1.6.7.AppImage

Step 3: Run the AppImage

Once the AppImage is executable, you can run it directly from the terminal or by double-clicking it in your file manager.

./Obsidian-1.6.7.AppImage

Step 4: Optionally Move the AppImage to a System-Wide Directory

If you plan to use the application frequently, you may want to move the AppImage to a system-wide directory like /opt for easier management.

Create a Directory:
Terminal window
```
sudo mkdir -p /opt/obsidian
```

Move the AppImage:

sudo mv ~/Downloads/Obsidian-1.6.7.AppImage /opt/obsidian/Obsidian.AppImage

Step 5: Create a Desktop Shortcut

To integrate the AppImage into your application launcher (so you can search for it like any other installed app), you’ll need to create a .desktop file.

Create a .desktop File:

Open a text editor and create a file named obsidian.desktop in ~/.local/share/applications/:
Terminal window
```
nano ~/.local/share/applications/obsidian.desktop
```
Add the Following Content:

   [Desktop Entry]
   Type=Application
   Name=Obsidian
   Icon=/opt/obsidian/obsidian.png
   Exec=/opt/obsidian/Obsidian.AppImage
   Categories=Utility;Editor;
   Terminal=false
   MimeType=x-scheme-handler/obsidian;

   Make sure to adjust the paths to match the location of your AppImage and icon.

3. **Update Desktop Database**:

   After saving the file, run the following command to ensure your system recognises the new desktop entry:

   ```bash
   update-desktop-database ~/.local/share/applications/

Log Out and Back In:

If the application doesn’t appear in your launcher immediately, try logging out and back in.
