CREATE DATABASE myproject;
CREATE USER myprojectuser WITH PASSWORD \'passwo         


        

Answer 1

As per the docs psql -c 'command;'

psql -c 'CREATE DATABASE myproject;' -c "CREATE USER myprojectuser WITH PASSWORD 'password';" -c 'GRANT ALL PRIVILEGES ON DATABASE myproject TO myprojectuser;'

Answer 2

As @horse suggested -f filename is a better option. You can also put them into a variable using a here document and execute it with the -c option .

read -r -d '' my_sqls << EOM
CREATE DATABASE myproject;
CREATE USER myprojectuser WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE myproject TO myprojectuser;
EOM
psql -c "$my_sqls"   # running all  the lines.
