Recently when I was sitting on my couch in the living room, I have realised that the iTumes running on my iMac (which is in a different room) is playing bit too loud. As it was too comfortable to get up and go to the machine to reduce the volume I found an easy method using the OS X terminal. Here is how I did it.

Connected to the iMac using ssh from my laptop.

Entered the following code

Here the volume scale is from 0 to 100.

That’s all.
