Как сделать так, чтобы индикатор выполнения оставался на экране в bash?

Я новичок в сценариях bash и хотел бы сделать простой индикатор выполнения

init pb
do stuff
pb add 10%
do other stuff
...

Но сценарии, которые будут обедать, будут печатать какой-то журнал, и я не хочу, чтобы индикатор выполнения исчезал, я бы хотел, чтобы он оставался внизу экрана. Это возможно ?

большое спасибо,

Артур

Вот мой код:

#!/bin/bash
echo 'Welcome to autoIrc'
echo 'This will automaticly create a gephi file for you'
echo 'I suggest running the script in a screen if you are with ssh'
# Are you sure ?
location=`pwd`
echo "We are in $location. Do you want to install the script there ? [Y/n]"
read -p 'Y/n >' confirm
if [ $confirm != "Y" ]
then
    echo "I am exiting"
    exit
fi
clear
echo 'Cleaning up...'
echo -e "\e[100m"
echo "We are in $location."
echo "Files list here:"
echo `ls ./`
echo "File list in ../"
echo `ls ../`
rm ./ircsnapshot -R
echo -e "\e[49m"
clear
# Okay, now, go on
echo 'First, a bit of config'
read -p "Please enter the bot nickname >" nickname
read -p "Please enter the bot username >" username
read -p "Please enter the bot realname >" realname
read -p "Now, please enter the number of seconds between commands >" throttle
read -p "Please enter the server adress >" server

РЕДАКТИРОВАТЬ: «Дубликат» не показывает индикатор выполнения, который остается в нижней части экрана.
