1. pipe "|" is a symbol usually used to seperate two commands on a terminal, its main functionality is output of first command from left side serves as input to subsequent command(s). 2. SQL injection is sending harmful information through search box which may lead to damage to data in a SQL database. To mitigate it we should avoid dynamic SQL commands.
