I want to find how can I check the disk usage in linux as in windows task manager.
I mean, I don't want to find out how much free space is there on the partition or something like that, I want to find out how much is the disk used at a given moment.
Here's a gif: https://i.gyazo.com/4a91e7ed2e519d6fe628811d7c03d6c3.gif
It's used more when I open a program.
