df -h==>human-readable print sizes in human readable format(e.g.. 1k 234M 2G)

df -H==>human-readable print sizes in human readable format(e.g..1k 234M 2G), likewise, but use powers of 1000 not 1024

df -a==>include dummy files systems

df -k==>like --block-size=1K

df -m=>like --block-size=1M

df -T==>print file system type
