I have a `grep -o '100%'` piped after a `wget`, so I'm only notified that `wget` completed the download, without useless information on screen. But each `100%` is printed on a new line, and I don't like this flood! So, is there a way to `tr` the newlines into spaces, by piping `tr` after `grep`? All I got was no result, each time I tried...
