I was going through the script for a cold backup, and I saw the statement "select 'host cp '|| name ||' &dir' from v$datafile order by 1;" I want to know why we need to add 'host' before the cp command. Thanks in advance.

This script assumes that you will be running a SQL script from SQL*Plus, but you really want to perform an OS command. In this case, you will be using the Unix/Linux copy command, cp, to copy a file. In SQL*Plus, the "host" command will execute any OS command outside of SQL*Plus before returning control to the user.
