Is it possible from a Linux command line to find out what memory I have? By which I mean how many slots I have, how many are filled, and what by?
I've used tools like Crucial's memory scanner (on Windows) in the past to determine what is in a system and from there to decide what best to upgrade with, and I'm looking to do something similar on Linux. The fact that Crucial can do it suggests the info is there somewhere.
If not at the commandline, then GUI-based would suffice for now (but would limit usefulness).
Initially I'm looking for something that works on Ubuntu 12.10 (64-bit).
