bash & postgres

Hi,

I'm trying to pass variables on a bash script embedded with psql commands.

cat header.txt

"to1","from1","subject1"
"to2","from2","subject2"
"to3","from3","subject3"
"to4","from4","subject4"

cat b.sh

#!/bin/bash
two="2"

psql -h localhost -U postgres -d mobile -c "create temp table header (

field_1 text not null,
field_2 text not null,
field_3 text not null

);

\\copy header FROM header.txt CSV

SELECT * FROM header limit "$two"; "

When I execute b.sh
================================
ERROR: syntax error at or near "\"
LINE 10: \copy header FROM header.txt CSV
^

How do I use \c (or any other psql commands beginning with a "\") in a
bash script?

Thanks.
