I need a command or a script which can give following information for all unix flavors 1)Total Hard Disk Capacity, it should include all hard disk installed 2) Free Space of Hard Disks 3) Used Space of Hard Disks

>Total Hard Disk Capacity, it should include >all hard disk installed (Assuming you meant hard disks mounted by the system) You can have a drive installed, but the system won't know options #2 & #3. Your best solution is to pipe a df -k command through awk and have it total up the relevant columns for you. -jim

Yeh Jim, Thanks for the input. I mean all physical disk drives. How about this command, can you verify this ? 1) Below Command will give you Total Hard Disk Capacity in MB df -k|sed 1d|awk '{total += $2} \ END {print total/1000}' Below Command will give you Available Space(Free Space) in MB 2) df -k | sed 1d | awk '{total += $4} \ END {print total/1000}' -P

Yeah, that's basically what i mean. Sorry i can't test at the moment. i'm on a win98 with cygwin and the df command output is different. You can make those into one command by making the variable names (total, avail, used) different for each column. Check this script for what i mean: http://www.computing.net/unix/wwwboard/forum/3886.html -jim

In HP-UX N class use the command bdf. it is Berkley version.It gives total hard disk space,free space,used space,filesystem,%used and mount point.
