Discuss process management in shell scripting, including background tasks and job scheduling with cron.

Process management is an important aspect of shell scripting, allowing you to control the execution and scheduling of tasks. In this context, we'll explore two key concepts: running processes in the background and job scheduling using cron. 1. Background tasks: In shell scripting, you can run tasks in the background, allowing them to execute concurrently with other processes.
