bash 51

In Bash scripting, the wait command is used to pause the execution of a script until specified background processes are completed. When a process is run in the background (using &), it is executed concurrently with the script. The wait command can be used to block further execution until those processes have finished. How does the -f option enhance the wait command in Bash 5.1+? Introduced in Bash version 5.1, the -f option for the wait command is a powerful tool. It not only pauses script execution until the specified background process completes, but it also preserves the exit status of the waited-for process.
