Shell Scripting

Shell scripting involves writing scripts using shell languages like Bash to automate tasks and workflows. In the context of Docker, shell scripts are commonly used in Dockerfiles as part of RUN instructions to set up the container environment, install packages, or configure applications. They are also used as entrypoint or startup scripts (via ENTRYPOINT or CMD) to initialize services when a container starts. Understanding variables, conditionals, loops, and functions in shell scripting helps you write more efficient Dockerfiles and manage complex container setups.
