what is the difference between -h and -H ?

samba:/home/backup # df -h /home/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb2 34G 8.6G 26G 26% /home
samba:/home/backup # df -H /home/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb2 37GB 9.2GB 28GB 26% /home

what is the difference between -h and -H on the command line of du?

Is one reporting size in terms of 1kbyte=1,000 bytes and the other reporting 1kbyte=1024 bytes?

Just curious.

Thanks.

You should be able to type "man df" and see:

Thank you.

Onve again, I display my newbie-ness with linux.
