[SOLVED] linux finding all drives .

[91change]

sfdisk -s

The above command provides whole drives with their size in blocks ...How can i find the size in bytes ?



Thanks,

If you run it with 'sfdisk -l', you will get a line like

Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

There you have the size of a block.

That is great .But unluckly my box linux doent have sfdisk .

I am going for fdisk -l

i would like to write a script that will provide me --disk name and disk size --in two dimensional arry or in a map .

i am new to scripting .

i tried
fdisk -l | grep Disk | grep "byte" | awk '{ print $1}
but i dont know how can i make it in an arraray.


I think i suceeded in conveying my questions in a good english . i wrote below to make u understand ...Sorry for my bad english .

clarification on "array"
string name[10];
int size[10] ;

for each i in name , correspoding i th element size indicates its size .....

Erm, are you aware of "df -h"?

i want to know full disk size ...and i am not mounting devices.

but using df -h ,i can see only disk partions ..not disk size whole

Here's a sample script that does what you want:

#!/bin/bash

typeset -i CT=0
TMPFLE=/tmp/tmp.tmp

fdisk -l | grep "^Disk" > $TMPFLE
while read LNE
    do
        CT=CT+1
        DSK[$CT]="`echo "$LNE" | awk '{print $2}'`"
        SZE[$CT]="`echo "$LNE" | awk '{print $5}'`"
        echo "${DSK[$CT]} ${SZE[$CT]}"
    done < $TMPFLE
echo "Disks found: $CT"

Your answer is very interesting ....

Without creating tmp file , Can we do this ?

EDIT: Forgot to mention that bash only supports one dimension arrays.
