Shell Programming and Scripting

Code:

You seem to be multiplying by 1024 to the power of 6.

echo "1024 ^ 6"|bc
1152921504606846976

To multiply by 1024 to the power of 6 for example:

size=1000000
echo "$size * (1024 ^ 6)"|bc
1152921504606846976000000

Have you considered working in more manageable units?

try this!!!

Code:

echo "$size  * 1152921504606846976"|bc

Thank u all

But I have a qn here... I need to assign that value to a variable. Could u please help me???

I tried in so many ways... but couldnt find the exact way...

?????????

Please don't bump up questions, that against the rules.

It is possible that your script has defined the variable "value" as an integer (typeset -i value). The shell integer variables cannot hold very large numbers. Just hold them in a character field. Also, most versions of "expr" cannot deal with very large numbers.

To ensure that your variable "value" is a character variable "unset" it.

size=1000000
unset value
value=`echo "$size * (1024 ^ 6)"|bc`
echo $value
1152921504606846976000000
