Let’s see you want to download a series of file from somewhere.
Which is having sequential filename.

This can be easily done with a shell script.
such as below:

for i in {1..113}
do
echo $i
done

while am at it, why not make a PDF file out of the images file.
this may require ImageMagick to be installed first.

yum install ImageMagick -y

So, the final script would be something like..

for-loop-bash

#!/bin/bash
 
  mkdir z
  cd z  
  for i in {1..113}
    do          
      # go get the image.
      /usr/bin/wget https://dev.namran.com/ss/IMAGE-$i.jpg -O $i.jpg
    done        
  # make pdf from jpg list
  convert `ls -1v` ../1st-session.pdf
  mv ../1st-session.pdf ~/public_html/download/

Done.
