Question

The entire box. How many gigs is everything using?

And how do I check total?

Answer 1

At a command line, type

df -a

This will list each device and usage information.

You might find

df -h

more readable, since it gives quantities in Gb or Mb, etc.

Answer 2

As suggested by others, du and df can easily do the job, but baobab (see screenshot below) is a great tool for analysing disk usage of whole file system or specific folders.

If you are using ubuntu, then baobab is already installed. Start it from Menu->Accessories->Disk Usage Analyzer or type baobab in a terminal window.

Answer 3

du . -h --max-depth=1

lists the size of all the folders in the current directory (or at a location of your choice)

Answer 4

Here are some approaches:

df -h

Or install the totally awesome kdirstat graphical utility:

Answer 5

du -sh folder

tells you how much folder is taking space. You can list multiple directories at once or use *.

df -h

tells you the total space of each mount point.

You can omit h (human readable) from both if you want to know the exact amounts.

Answer 6

df -h

Although, this question probably belongs on superuser.com

Answer 7

du

Answer 8

There is also ncdu.
