I created a file in linux vi command shell but am stuck i need to:

suspend the editor and show that it is suspended or stopped but still active (in your job list). List the file. And resume the editor. (you can either show screen capture or describe commands). Check what is a process ID of editor and parent its process ID

List your directory that contains mynumber file in a long format. Explain the current file permission info. Change file permission mynumber so that your group can read only
