Question Download images from the first column and rename it with the second column in a loop: Please help!

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

Code:
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

NAME
mrename - program to rename files SYNOPSIS
mrename 'pattern' prefix [option] DESCRIPTION
This manual page documents briefly the mrename command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. mrename is a tool for easy and automatic renaming of many files. The 'pattern' is the pattern to search files to rename (quoted to avoid that bash resolve it), and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or moving files in the new name are explained below. All parameters are needed, and you have to stay and launch the script in the same direc- tory of the files to be renamed. The program should be able to write in this directory. OPTIONS
There are only the following three options. -c The option -c will copy each file with the new filename. -m The option -m will move each file in the new filename. -h Display help. EXAMPLE
If you have a directory with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc.. (that is item0prof.jpg, item1forp.jpg etc..) do this: cd /path/to/the/images mrename '*.jpg' item -c to copy each matching file into another with the new name mrename '*.jpg' item -m to rename each file without keeping a copy with the previous name Word-Wide-Web: http://alfalinux.sourceforge.net/mrename.php3 AUTHOR
: Giancarlo -rofus- Erra e-mail: rofus@mindless.com This manual page was written by Dr. Guenter Bechly <gbechly@debian.org>, for the Debian GNU/Linux system (but may be used by others). It is distributed under the GPL just like mrename itself. October 22, 2000 MRENAME(1)
