Linux, checking how much space is used in each partition

At the bottom of every tab/window in nautilus it will display how much free space is on the drive you are currently browsing if you have no folders/files selected.

"This is a reminder on the usage of sort with df:

df -alhk | sort -nk2 # list disk usage and sort by used blocks
df -alhT | sort -hk3 # show and sort by human-readable usage
df --si | sort -hk3 # (this one doesn't show the empty file systems)
df --si | sort -nk5 # sort by percentage full

Only file systems starting with '/dev' are disk partitions:

df -h | grep ^/dev

show partition type too, and hide some non-disk filesystems:

df -h -T
df -h --output=source,fstype,size,used,avail,pcent,target -x tmpfs -x devtmpfs

a better view:

pydf

list storage blocks:

lsblk

for block device attributes:

blkid

more time consuming but useful tools for examining disk usage:

du
du | xdu
ncdu
xdiskusage

Use the df command in a terminal window. I like to use the -k option to get the size in KBytes.
