free -m
does not seems to include memory used by RAM disks (tmpfs filesystems). Maybe because it's something in the kernel space?
How do I get the real memory usage (or it's opposite, free memory) including the allocated space of filesystems that reside in RAM like tmpfs
?
I currently check for the memory usage by running df -h
and adding the "In use" numbers to the -/+ buffers/cache
number. Is there a command available that gives me the real memory usage?
Best Answer
you can install htop via the terminal
then run htop in the terminal
disclaimer I guess this does not work on Lucid correctly
