How does the "d3fg" command work?

Question

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.

Answer 1

In fact, fg is "foreground" in Bash, but not in Vi(m). d3fg means:

d - Delete until...
3 - Do the next motion 3 times
f - Go to the next occurrence of the next character pressed.
g - The character to go to.

Thus, d3fg will delete up to (including) the third letter g on the line after the cursor.

Thus the following text, with the cursor on the 0:

01g2g3g4g5g6

Becomes after d3fg:

4g5g6
