Linux script file to create database in Oracle

To create oracle database, user and tablespace in linux, use the below script file. Please go through the script file carefullly before executing or creating the database, as the values of sga_target and pga_aggregate_target are provided very less


kasi.sh : 

cd $ORACLE_HOME
ORACLEHOME=$ORACLE_HOME
cd ../../..
cd oradata
echo "Please enter the database name"
read name
mkdir $name
cd $name
dir_path=`pwd`;
echo "YOUR FILES WILL BE STORED ON THIS DIRECTORY: $dir_path"

cat > 1.sql <<EOF
