Shell Programming and Scripting

hi guys- im trying to write a script to get both url and ip information. i think i can get it to work if i hardcode the url into the script, however what I rather have happen is the script ask the user to input a url. ive searched through the wget man and cant find anything there. i know this must be an easy fix, can anyone help?

ill try to break out what i think should happen

#!/bin/bash
wget (dont want to hardcode the url here, i want a prompt to go to user for url)
save url data to a file
read url from file to obtain ip address

i would like to use this so i can easily download a webpage and get its ip in one step

any help would be greatly appreciated

If you just want the IP address of a host, why don't you use host(1) or dig(1) ? Why wget ?

im hoping to get all of the url's information as well as the ip all in one scrippt

Code:

#!/bin/sh

read url
wget $url
host $(echo ${url#*//} | sed 's/\/.*//')

ill try this code out and see if it works for me.. thanks a lot for the code.

would anyone be able to detail exactly what each line is doing for me in easy to understand terms? i know what read, wget, and those things mean by definition, but knowing what they mean in real terms would help a lot.

Code:

read url

Read user input, the url, into the variable named 'url'.

Code:

wget $url

Fetch the contents of the url.

Code:

host $(echo ${url#*//} | sed 's/\/.*//')

echo ${url#*//} - removes the 'http://' part from the url, if any.
sed 's/\/.*//' - removes the file path from the url

Only the host name remains which is passed onto host(1) to get the IP.
