How to check who or what is using up the RAM?

Question

I am using a shared workstation. Typing free -h returns me

              total        used        free      shared  buff/cache   available
Mem:            31G         30G        232M        292M        1.0G        608M
Swap:          2.0G        997M        1.0G

How do I check what processes or who is using the memory?

Answer 1

You can use top (just type "top"). A "better top" is htop - just install it:

sudo apt install htop

... and use it

htop
