Calculating Disc Space
Ok....
Can someone please point me in the right direction.
I simply want to know how to take the results of a dfspace or df command and be able to know how to determine how much disk space is either used or remaining.
1$ dfspace
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 32768 19896 40% 1227 15% /
/dev/hd2 802816 277248 66% 1035 11% /usr
/dev/hd9var 32768 22480 32% 201 5% /var
/dev/hd3 65536 44680 32% 137 2% /tmp
/dev/hd1 16384 15568 5% 126 7% /home
/dev/lv00 98304 43992 56% 355 3% /versyss
/dev/lv01 6012928 1989648 67% 5022 1% /versyss/data
1$ df -k
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 16384 9948 40% 1227 15% /
/dev/hd2 401408 138624 66% 11035 11% /usr
/dev/hd9var 16384 11240 32% 201 5% /var
/dev/hd3 32768 22340 32% 137 2% /tmp
/dev/hd1 8192 7784 5% 126 7% /home
/dev/lv00 49152 21996 56% 355 3% /versyss
/dev/lv01 3006464 994824 67% 5022 1% /versyss/data
One section shows 512-blocks and the other shows 1024-blocks
I am sure there is a simple procedure for calculating disk space..
Please help =)

Hi Experts,
In a particular dir, I have many files *AJAY*.
How can I get total size of all such files.
I tried du -hs *AJAY* but it gave me individual size of all files.
All I require is summation of all.
Thanks,
