psql doesn't use parameters - it uses variables.
http://www.postgresql.org/docs/9.3/interactive/app-psql.html
In part <and not tested>:
echo "DELETE FROM part WHERE part.CUST_ID = :'del_id';" > custde.sql
psql --set=del_id=383373 --file=custde.sql
Note that based on your prompt (db=#) and the command "\i" you are already
using psql interactively. This not the same thing as "I need to run from
command line like putty tool".
Beyond this you need to learn about shell scripting to more readily
integrate psql into a complex process.
