Bash isn't doing the line wrapping. That's your terminal emulator. For example, if you're using screen, you can use ^A^R to turn off line wrapping. With xterm you can use the +aw option. Check the manual for your terminal emulator. > During script execution, I want certain lines to be overwritten.

It's a completely separate, noninteractive shell. And you don't get $COLUMNS because it's a noninteractive shell. You could try stty -a or something like that...
