"Command line" commands are very helpful. Is there a command to display the memory of each partition of my drives..?


You can use df like so:

df -h

which will show something like this:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda5        56G   47G  6.8G  88% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            940M  4.0K  940M   1% /dev
tmpfs           192M  996K  191M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            957M  5.1M  952M   1% /run/shm
none            100M   44K  100M   1% /run/user
  • This method is commonly used to make sure there is enough disk space, as that is a common cause of MySQL errors: df -h df -i – Armin Nehzat Jan 1 '15 at 7:39
  • -h, --human-readable print sizes in powers of 1024 (e.g., 1023M) – Stanislav Feb 25 at 12:47

Use the df command:

df -h

to give you information about the various mounted filesystems on your computer, and their free and used space.
