csh scripting and awk?

Hi, I'm trying to write a csh script (for all you csh haters, this is a task i was given in my college studies) and in that script I want to use awk. the problem is, that in the pattern in awk, there is the $1, $2, $3 (...) variables, representing fields of the file / input. Also, in csh scripting, there are $1, $2, $3 (...) variables, representing arguments for the script.

What I want to do is to compare the second field of the awk input to the third argument of the script, but that does some problem - lets say,

Code:

#!/bin/csh



.....

awk '$3 ~ $2' somefile

.....

but that doesn't work well.
Do you know of any solutions for this problem?

how about something like

Code:

awk $3' ~ $2' somefile

Doesn't work... how did you come up with that one?

alright, found it. it is possible to do:
awk -v expression=$3 '$2 ~ expression' file
a pretty nice way.
if you know any other ways, more elegants and such, you are free to give a comment ;)
