When we download something or install software via Terminal, we always see a number show the progress to us.
The number is changed, but it still in the same line.
How can I do in the bash?
I'm a new basher, help!

1[My answer](http://stackoverflow.com/a/1508589/45249) to [How can I erase the current line printed on console in C ?](http://stackoverflow.com/q/1508490/45249) may help. It is about [VT100 escape codes](http://www.climagic.org/mirrors/VT100_Escape_Codes.html). In bash, `printf "\x41"` outputs `A`. – mouviciel Dec 04 '13 at 08:13

The trick is to use \r instead of \n at the end of the line:
echo -n " 50% complete."$'\r'; sleep 1; echo "100% complete."
