Create a script that internally calls the Linux command 'ps aux' and saves the output to a file named unprocessed. txt (you do not need to append to an existing file, if a file already exists, simply overwrite it). The program should pause and display the following message to the screen: Press 'q' to exit or 'ctrl-c' to process the file and exit' If the user presses 'q', exit the program leaving the filename on the disk as 'unprocessed. txt'. If the user presses 'ctrl-c', then catch the signal (hint - covered in chapter 16) and rename the file to 'processed. txt' and then exit. You must build a signal handler to catch the ctrl-c signal and rename the file. g
