I'm building CLI app (on Linux) where user has to choose something and then I have to clear last line.
I tried several things:
fmt.Print("\r")
fmt.Print("\033[1")
And the cursor goes back to beginning of line, but do not clear the text from the last line.
What am I missing here?
You can use it that way
fmt.Printf("\033[1A\033[K")
\033[1A
- one line up \033[K
- delete the line
For example
fmt.Println("hello")
fmt.Println("world")
fmt.Printf("\033[1A\033[K")
will output only hello
as the world will be deleted
