How can I check disk space used in a partition using the terminal in Ubuntu 12.04 LTS? [duplicate]

The su command is completely irrelevant. The disk usage is the same for all users. Anyway, some relevant commands and their output on my system are:

terdon@oregano ~ $ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda7              68G   23G   43G  35% /
udev                   10M     0   10M   0% /dev
tmpfs                 800M  1.6M  798M   1% /run
tmpfs                 5.0M     0  5.0M   0% /run/lock
tmpfs                 3.2G   12M  3.2G   1% /run/shm
/dev/sda6             290G  256G   20G  94% /home
tmpfs                 3.2G  992K  3.2G   1% /tmp
none                  4.0K     0  4.0K   0% /sys/fs/cgroup
/dev/sdc1             466G  379G   88G  82% /media/terdon/Iomega_HDD

For a specific partition:

terdon@oregano ~ $ df -h /dev/sda7
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda7              68G   23G   43G  35% /

Alternatively, though this only lists the size, not the %used:

terdon@oregano ~ $ lsblk 
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk 
├─sda1   8:1    0  39.2M  0 part 
├─sda2   8:2    0  14.7G  0 part 
├─sda3   8:3    0  78.1G  0 part 
├─sda4   8:4    0     1K  0 part 
├─sda5   8:5    0     2G  0 part 
├─sda6   8:6    0 294.4G  0 part /home
├─sda7   8:7    0  68.7G  0 part /
└─sda8   8:8    0   7.8G  0 part [SWAP]
sdc      8:32   0 465.8G  0 disk 
└─sdc1   8:33   0 465.8G  0 part /media/terdon/Iomega_HDD
sr0     11:0    1  1024M  0 rom  

Conversely, you can use the du command to print directory size which will give you the disk usage of a partition if you run it on a partition's mountpoint: du -xsch /home for example. The -x option will "skip directories on different file systems," which is helpful if you have other mount points nested below the partition's mount point (typically /).


You can use df -Th to get the used space of partitions:

$ df -Th

Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/sda9      ext4       22G   16G  4.8G  77% /
none           tmpfs     4.0K     0  4.0K   0% /sys/fs/cgroup
udev           devtmpfs  1.5G  4.0K  1.5G   1% /dev
tmpfs          tmpfs     297M  1.4M  295M   1% /run
none           tmpfs     5.0M  4.0K  5.0M   1% /run/lock
none           tmpfs     1.5G  616K  1.5G   1% /run/shm
none           tmpfs     100M   68K  100M   1% /run/user
/dev/sda5      fuseblk    53G   34G   19G  65% /media/Songs
/dev/sda7      fuseblk   103G   90G   14G  88% /media/Data
/dev/sda6      fuseblk    69G   34G   35G  50% /media/Movies
/dev/sda1      fuseblk    49G   36G   14G  72% /media/guru/0C64A7F864A7E326

You can also provide it with a specific partition if you want to view disk utilization of only that partition:

$ df -Th /dev/sda9

Filesystem     Type  Size  Used Avail Use% Mounted on
/dev/sda9      ext4   22G   16G  4.8G  77% /

You can also use pydf or discus to get better representation in terminal. You need to install these if you want to use it. Type:

sudo apt-get install pydf in terminal to install pydf.

$ pydf  
Filesystem Size Used Avail Use%                                      Mounted on
