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

If you echo without the newline character echo -n "Something", you can use \r with your next echo to move the 'cursor' to the beginning of the line echo -e "\\rOverwrite something".

#!/bin/bash

CHECK_MARK="\033[0;32m\xE2\x9C\x94\033[0m"

echo -e "\n\e[4mDoing Things\e[0m"
echo -n "doing thing 1..."
sleep 1
echo -e "\\r${CHECK_MARK} thing 1 done"

Just be aware that if your new string is shorter that your old string, the tail of your old string will still be visible. Note the done.. in the gif above.
