How can I check disk usage using ssh?
Solution 1:
You can use df -h to see the free space, used space, and total space of all partitions on the system.
Solution 2:
Are you wanting to see the disk usage on the SSH remotely? As in, "log in to SSH server and then show the disk usage"?
If so...
ssh user@host "df -h"
That's assuming you have key logins enabled so it doesn't prompt you for a password.
