What is Shell Scripts?
Shell scripts are a powerful tool used to automate repetitive tasks and perform complex operations. They are essentially text files containing a sequence of commands to be executed by the shell (such as Bash or Zsh). By leveraging shell scripts with tools such as cron, you can efficiently automate tasks related to PostgreSQL and streamline your database administration processes.
