Overwrite last line on terminal

Question

My bash-script looks as following:

echo \"Description:\"
while [ $finishInput -eq 0 ]; do
read tmp
desc=\"$desc\"$\'\\n\'\"$tmp\"
if [ -z \"$tmp\" ]; then
fi         


        

Answer 1

In your example you delete the text at the same line. When you want to return to the previous line use \e[1A, and to clear that line, use \e[K:

echo 'Old line'
echo -e '\e[1A\e[Knew line'

When you want to go N lines up, use \e[A
