Shell Programming and Scripting
1

Dear Friends,

I have a very little knowledge on shell scripting. I am stuck with a problem for which I need an expert advice.

I have a .txt file "image_urls.txt" which contains the data like this

imageurl

(h t t p urls above)

Since the images names are not unique they are getting overwritten as soon as its downloaded. So I want to rename the images in first column with the second column value (vin_series) in a loop (line by line), one by one image.

The renamed images will be there in the directory and mapped in the database.

Please help me on this.

Regards
Praveen

Use --output-document option with wget to specify the file name while downloading:

while IFS="|" read url img skip
do
  [[ ! -z "$img" ]] && wget --output-document="${img}" "${url}"
done < image.urls.txt
