How to see filesystems and space used

df command reports file system usage

Example: df –k,


-a, --all
include filesystems having 0 blocks
-B, --block-size=SIZE use SIZE-byte blocks
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
-H, --si
likewise, but use powers of 1000 not 1024
-i, --inodes
list inode information instead of block usage
like --block-size=1K
-l, --local
limit listing to local filesystems
do not invoke sync before getting usage info (default)
-P, --portability
use the POSIX output format
invoke sync before getting usage info
-t, --type=TYPE
limit listing to filesystems of type TYPE
-T, --print-type
print filesystem type
-x, --exclude-type=TYPE
limit listing to filesystems not of type TYPE
display this help and exit
output version information and exit
