Can't open an app as root. Sudo command not found I'm trying to install the torrent downloader Vuze and every time I try to open the Vuze Installer via the terminal, in my case,

sudo /Users/naza/Downloads/VuzeInstaller.app


after put the password the therminal says

sudo: /Users/naza/Downloads/VuzeInstaller.app: command not found


I'm a new MacOS user but I know I can install the app by just going root and log in as root user in another session but I read that is recommended to do it with sudo via the terminal.

I just installed MacOS Catalina, it would be weird if something, as the sudo command, is missing.

I also tried to use the SU command 

su /Users/naza/Downloads/VuzeInstaller.app


but it doesn't seem to work. The terminal answers su: Sorry. I read that's because the command isn't on for non-root users, same if I try sudo su  /Users/naza/Downloads/VuzeInstaller.app, the terminal respond su: unknown login: su.
You need to execute the unix executable, normally found in some.app/Contents/MacOS. To browse the app contents, right click on the app, and choose "Show package Contents".

You can simply drag and drop the executable in a Terminal window to get its path. Or you can right click, hold alt and choose "Copy as pathname". 

Run the command below first, using sudo on any executable is not recommended. 

/Volumes/Vuze\ Installer/Vuze\ Installer.app/Contents/MacOS/JavaApplicationStub


This of course assumes that you have already mounted the .dmg file downloaded from Vuze website.
