A wild guess here: you are extracting the IP variable from a .txt file — if that’s a Windows file, or is encoded Windows-style, lines end with \r\n. You take the newline away, but what if there’s a \r in it that’s making you go back to the beginning of the line? Quick dirty fix … Read more
You should be able to erase an asterisk by writing the characters \x08 \x08. The \x08 will move the cursor back one position, the space will overwrite the asterisk, then the last \x08 will move the cursor back again, putting it in the correct position to write the next *.

EndOfMessage The string after << indicates where to stop. To send these lines to a file, use: cat > … Read more

There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn’t set a return value if you really want to get down to the nitty gritty.
