Can confirmation be bypassed in CLI while installing software or upgrading?
 

I don't know why I want this, but is there a way the or command could bypass the confirmation stage? It's always occurred to me shouldn't there be some command parameter for install/upgrade that does the work?

Let me give an example. Suppose I want to install Variety, the wallpaper changing application. Now, I know that I want to install the software with all the dependencies it requires to install/run - the entire package. So, isn't it obvious that I would press Y when aptitude shows the info what it's going to download/install and asks for permission?

I can't, however, imagine scenarios when seeing that information I'd change my mind and press N to abort the install/upgrade procedure.

Did you check to see what the manpage had to say ?.

For apt-get, yum, and zypper, append -y after the package manager command, and before the name of the package(s) to install.

Thank you for directing me that way. Actually, never went down to the -y part. Learnt the lesson!

And also thanks to Ihatewindows522.

Be careful with that option, though. If you want to install a package that conflicts with an already installed package you might see half of your system being removed because of this option, while you would see that problems will arise when being asked for confirmation instead.

Will sure remember that, Tobi. I'm not certain I'll ever use that option - I just posted this thread out of a moment's frustration :) .

Believe me, if you want to give it a few tasks to run when you gotta run, you'll be glad you've got it. ;)
