Pay attention..
WTF! It's like being back at school! I merely answered you in a honest manner as I had literally just posted.. despite the fact that it was obvious that you had an axe to bear regarding the use of Linux Mint.. For one
Cash Tribe has a laptop not a desktop and I'm well aware that your statement was more relating to
'things are harder to do using Linux Mint than Windows' but if I had wanted to do what you were asking, I would of just Googled it (like many other things when using Linux Mint)
Something like:
identify *.jpg |grep -o "[[:digit:]]*x[[:digit:]]*" or
find /home/<user> -type f -exec file -i {} + | grep video
Admittedly I'm not saying these commands will work? but at least it'll give you the idea.. I guess the point your are trying to make is that things can be a lot more complex using Linux Mint and I'd agree. However
Cash Tribe hasn't gone into depth about what he wants to be using it for, merely '
will running Linux/Ubuntu be less aggressive on the ram as well as processor?' (of his laptop)
The reason I'm taking an interest in this thread now is that the other two Linux advocates haven't posted yet and I'm speaking up for the OS. It's all about what you intend to use it for. No hate here!!
