I mounted an apple time capsule in /etc/fstab as cifs type to /media/time_capsule. I now want to look at directory file sizes to help me clean out the drive.

I usually use the command below to list human readable sizes for files and directories:

ls -lh
but all the directories show up with 0 size! Not sure why / how to let me view directory size in terminal with ls. Update an index?
