Modify rnfile such that it will keep a copy of the old existing file (if available) before the renaming operating. Assume that apple.txt will be renamed as orange.txt. When the command “./rnfile apple.txt orange.txt” is executed, the script will first check whether orange.txt exists under the given path or not. If the file exists then orange.txt will be renamed as orange.txt_old before renaming apple.txt as orange.txt. Make rnfile an executable shell script; try to rename a file to a filename that already exists. Show your shell program and its output to the instructor.
