Scroll problems with empty PS1
Frage
If I scroll up through the history and come across a long line that wraps, then scroll back down, the lines will be scrambled.
I have read around that this can be caused by incorrectly escaping color codes, but this happens even with an empty PS1, e.g.
export PS1=""
In response to comment
echo "[$PROMPT_COMMAND]"
[]
echo "[$PS1]"
[]
Lösung
Just press Ctrl+L
to refresh the display.
I think the problem is more with Bash not knowing long commands are broken into multiple lines.
