I wrote my first Bash Script with a updating Loader.

first.sh

#!/bin/bash
# Author : Teddy Skarin

# 1. Create ProgressBar function
# 1.1 Input is currentState($1) and totalState($2)
function ProgressBar {
# Process data
	let _progress=(${1}*100/${2}*100)/100
	let _done=(${_progress}*4)/10
	let _left=40-$_done
# Build progressbar string lengths
	_done=$(printf "%${_done}s")
	_left=$(printf "%${_left}s")
	_mes=$(printf "Okay")

# 1.2 Build progressbar strings and print the ProgressBar line
# 1.2.1 Output example:
# 1.2.1.1 Progress : [########################################] 100%
printf "\r Progress : [${_done// /#}${_left// /-}] ${_progress}%%"

}

# Variables
_start=1

# This accounts as the "totalState" variable for the ProgressBar function
_end=100

# Variables
_starttwo=1

# This accounts as the "totalState" variable for the ProgressBar function
_endtwo=50

# Proof of concept
