Question

In linux we can change the variable of http_proxy in terminal by export http_proxy=http://x.x.x.x:x. But I want to do it with script. So I have following code:

#!/bin/bash

FILE="_reliable_list.txt"

for line in $(cat $FILE)
do
    proxy="http://$line"
    export http_proxy=$proxy
done

At the end on the same terminal when I check the value of variable http_proxy, it is null.
I want to read from file proxy addresses and export them to http_proxy variable, and after use it with wget. Simply I want to automate this code:

export http_proxy=http://x.x.x.x:x
wget mysite.com

If any other ideas I will be very glad.

You can change the script to embed wget call, assuming a new file containing urls:

#!/bin/bash

URLS="_url_list.txt"
FILE="_reliable_list.txt"

i=1
for line in $(cat $FILE)
do
    export http_proxy="http://$line"
    wget $(head $i $URLS | tail -1 | tr -d '\n')
    let i++
done
