Describe how forking works, and how it affects the parent process.
What will be an ideal response?
When executing compiled programs or shell scripts, the BASH shell that interprets the command you typed creates a new BASH shell. This creation of a new subshell is known as forking, and it is carried out by the fork function in the BASH shell. The new subshell then executes the binary program or shell script using its exec function. After the binary program or shell script has completed, the new BASH shell uses its exit function to kill itself and return control to the original BASH shell. The original BASH shell uses its wait function to wait for the new BASH shell to carry out the aforementioned tasks before returning a prompt to the user.
