Integrating Bash Functions into Perl Scripts

Often in development, there is a need to leverage existing bash functions within Perl scripts to utilize shell capabilities or to integrate with system-level operations seamlessly. This post explores how Perl can interact with bash, allowing you to call bash functions directly from within your Perl code, complete with examples of different methods to achieve this integration.
