Grep problem

Hi there, this is a very simple question.

When I do grep -c "PWD" filename, I get 5. This means the filename contains 5 lines of "PWD" occurence.

I tried to assign to a variable. int= grep -c "PWD" filename

When I typed echo $int
The output:
5

[unix..]
I get an empty line space. Now I cannot do any arithmetic operations because $int will always be 0 rather than 5.
How can I solve this problem?

Try the following:

Code:
int=`grep -c "PWD" filename`
