How do i clear a specific Line?

I have a program to load up my computer and say "booting up, please wait…")
but I wanted it to go with the dots going up like "." ".." then "…" However When i used "clear line" it didn't and went on the other line
like this:
Booting Up, Please wait.
Booting Up, Please wait..
Booting Up, Please wait…
Is there a way to have this on the same line?
Here is the code i'm on about

print("Booting Up, Please wait.")
sleep(1)
term.clearLine()
print("Booting Up, Please wait..")
sleep(1)
term.clearLine()
print("Booting Up, Please wait…")
sleep(1)
term.clearLine()

Simple, put the cursor back on the line…

local x, y = term.getCursorPos()
print("Booting Up, Please wait.")
sleep(1)
term.setCursorPos(x,y)
term.clearLine()
print("Booting Up, Please wait..")
sleep(1)
term.setCursorPos(x,y)
term.clearLine()
print("Booting Up, Please wait...")
sleep(1)
term.clearLine()

Well, since you are just adding '.'s you could just do

write("Booting Up, Please Wait.")
sleep(1)
write(".")
sleep(1)
write(".")

… which works because "write" doesn't perform a line break like "print" does. And you can trim it down further:

write("Booting Up, Please Wait.")
textutils.slowPrint("..", 1)

Seriously though, this kind of thing is annoying for your users.
