Create schema with in a specific database from a script file

Hi,

   I have to write script for psql in a xyz.sh file which should create a schema in a specific data.In psql prompt I achieve it like --

postgres=# \c ABC

ABC=# create schema authorization myschema

     In xyz.sh I executed the following script ---

su -c "psql -c \"\c ABC  \"" postgres

su -c "psql -c \"create schema authorization myschema\"" postgres

In the terminal got message “connected to ABC database”. But schema created with in postgres database not with in ABC database.

What should be the proper script ?

Thanks and Regards,
