How can I download and set the filenames using wget -i?

Question

I wanted to know how to define the input file for wget, in order to download several files and set a custom name for them, using wget -i filename

Analog example using -O

wget -O customname url

Answer 1

-O filename works only when you give it a single URL.
With multiple URLs, all downloaded content ends up in filename.

You can use a while...loop:

cat urls.txt | while read url
do
    wget "$url" -O "${url##*/}"  # <-- use custom name here
done
