Admitted that rubin's way is much more clearer and readable, you can pass variables also interrupting and resuming the awk code by the means of single quotes, like I posted before.

The problem is that before I made a mistake, you also need to add a couple of double quotes to complicate things a little bit more Smilie

Code:
awk '$3=="'"$MONTH"'" {print $1, $2, $3, $4, $5, $6}' *.hits

Here goes another unconventional way of passing variables to awk:

Code:
echo "Enter month: "

read MONTH

awk '/'$MONTH'/ { print ... }' file

Caveat emptor:
The above approach does not work if the variable has whitespaces, newlines or certain special characters ( |, /, ...) in it.
So it's always recommended using the conventional way -v var=... .
