Automation script to download and extract decompressed files using bash scripting

Question

I created a script here and the script is all about checking the disk space if the disk space had enough space then it will download the file needed after that it will extract the file 5 times and it must not extract the last tar.gz file . But when I executed the script I got a problem here. For the extract side it will just extract 1 time but I already out it 5 times.

#!/bin/bash

outout=$(df -h)
file=$(awk -F = '{print $2}' config.txt)
filename=$(echo "$bundle" | awk -F / '{print $11}')
diskspace=$(df -h /var/ | sed '1d' | awk '{print $5}' | cut -d'%' -f1)
allowed=10

address=$(awk -F = '{print $2}' newconfig.txt)

if [ "${diskspace}" -gt "${allowed}" ]; then

#       cd "/var/"
        wget $bundle
else
        echo "Not enough space to download the bundle"
        echo $output
    exit
fi


 i=0
for tarfile in *.tar.gz
                        do
                         $(($i++))
                         [ $i = 5 ] && break
                tar -xf "$tarfile"
 done

For the config.txt https://www.google.com.ph/files.tar.gz

files.tar.gz is composed of 5 tar inside

files1.tar.gz -> files2.tar.gz - > files3.tar.gz -> files4.tar.gz - > files5.tar.gz

What should I do to extract it five times until files5.tar.gz will display and it must not be extracted.

Help is greatly appreciated.

Since I couldn't figure out the exact code you wan't, I would give a example code how to use while loop instead

i=0
tar xf files.tar.gz
while [ $i -lt 4 ];do
 ((i++))
 tar xf files${i}.tar.gz
done

Or use for to do the same thing.

for i in "" {1..4};do
  tar xf files${i}.tar.gz
done

These code executes following command

tar xf files.tar.gz
tar xf files1.tar.gz
tar xf files2.tar.gz
tar xf files3.tar.gz
tar xf files4.tar.gz
