i want to disable command+q shortcut

You can't disable it because it is system shortcut. But you can add another shortcut over it. I found useless command to link with cmd+Q

1. go System Preferences / Keyboard / Shortcuts

2. Select Accessibility and activate Zoom section by clicking box.

3. Select "Turn focus following on or off" and hit the "Add Shortcut" button.

4. Add cmd + Q command to this shortcut.

You done.

Now Command+q shortcut is useless.

Non-trivial

Try some of these web pages. If they do not help, then Google "Disable Command-Q" and you may find something that helps
