Easily Understand Your Linux RAM Usage With Smem

Linux memory usage can be difficult to interpret and hard to understand. With smem it’s easy to find out what memory a process is using, and which processes are using the most.



Commands:
sudo apt install smem
smem
smem -p
smem -k
smem -k -t
smem -u
sudo smem -u
smem -m -k -t
smem -w -k -t
smem -c pss -P firefox -k -t | tail -n 1
smem –pie name -s uss
