Loop Script with wget until exit is typed
Morning all,
I am attempting to complete the below script which will do the following (skip the ping part) using Bash.
Prompts the user to type in a URL to download, or to type exit to exit the script.
If a URL is typed, wget to download the webpage and then loop back to prompting for a typed URL or to type exit.
Basically the script continually loops back to prompting for a webpage after the wget is complete of the previous webpage until the user types exit into the prompt
This is what I have now but I'll explain below other things I've tried
I'm not asking for the answer (of course) just a push towards what I should be thinking about. As you can see, I currently have break at line 17 because, of course, without it, it currently will just continue to wget the URL as it gets stuck in an infinite loop. I am sure the solution is simple but I honestly can not wrap my head around how to get it to complete 1 wget and then go back to the url prompt repeatedly until the user types exit.

jigdo-lite
JIGDO-LITE(1) JIGDO-LITE(1)
NAME
jigdo-lite - Download jigdo files using wget
SYNOPSIS
jigdo-lite [ URL ]
DESCRIPTION
See jigdo-file(1) for an introduction to Jigsaw Download.
Given the URL of a `.jigdo' file, jigdo-lite downloads the large file (e.g. a CD image) that has been made available through that URL.
wget(1) is used to download the necessary pieces of administrative data (contained in the `.jigdo' file and a corresponding `.template'
file) as well as the many pieces that the large file is made from. The jigdo-file(1) utility is used to reconstruct the large file from the
pieces.
`.jigdo' files that contain references to Debian mirrors are treated specially: When such a file is recognized, you are asked to select one
mirror out of a list of all Debian mirrors.
If URL is not given on the command line, the script prompts for a location to download the `.jigdo' file from. The following command line
options are recognized:
-h --help
Output short summary of command syntax.
-v --version
Output version number.
--scan FILES
Do not ask for "Files to scan", use this path.
--noask
Do not ask any questions, instead behave as if the user had pressed Return at all prompts. This can be useful when running jigdo-
lite from cron jobs or in other non-interactive environments.
SEE ALSO
jigdo-file(1), jigdo-mirror(1), wget(1) (or `info wget')
CD images for Debian Linux can be downloaded with jigdo <URL:http://www.debian.org/CD/jigdo-cd/>.
AUTHOR
Jigsaw Download <URL:http://atterer.net/jigdo/> was written by Richard Atterer <jigdo atterer.net>, to make downloading of CD ROM images
for the Debian Linux distribution more convenient.
