how to output awk to a variable

Hi folks,
I am wondering how to output awk back to a variable.

I am new to Unix/Linux.
I am trying to get rid of a decimal number and put the output back in a variable for further use in the script. here is how I used awk:

var=$1
echo $var |awk '{print $1 *100}' | $var
echo $var

this gives me an error!
I don't necessarily need to use awk any suggestion of other commands that help get rid of the decimal is fine.

your help will be greatly appreciated!
Bashir

Hello,
If you goal is just to multiply $1 by 100 try this:

var=`expr $1 * 100`
echo $var

This should echo $1 times 100

thanks for the reply!

Actually the reason I am multiplying $1 by 100 is that I am trying to get rid of the decimal number if entered as the first command line argument.

for example:
if I enter 3.41 as the value for $1 the output of the awk should produce 340 getting rid of the decimal. and put the output in a variable instead of a file or the standard output.

Thanks again,

Hello,

I think this is what you want:

var=$1
var=`echo $var | awk '{print $1 *100}'`
echo $var

And if you want to remove the decimal point but don't know how many numbers will occur after the decimal, you can use:

var=3.2353
var=`echo $var | tr -d .`
echo $var
