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

If you want to run a script in a loop and not blow up your scrollback, you can use the following pattern:

while sleep 10s; do 
  echo -n $(script)
  echo -n -e "\e[0K\r"
done

Just replace the script command with your own.
