I would like to know how a "d3fg" command works in vi.
I have done some research on Google and found that
d is delete and
fg means foreground. Suppose, if we want to stop the session of vi and resume it afterwards, we can press Ctrl+z to come out of the vi session. Then type
fg to go back to the same vi session.
Now I wanted to know how this
d3fg works in vi editor.
