Curl and rename images using string from text file

I have a TXT file containing a list of URLs like:

website/media/945746/ui4Q9EJoUEmVLtUNhtRX.JPG John.JPG
website/media/226251/6epk0CUwnhofAjZMP2xp.JPG Kelly.JPG
website/media/658552/Q4qQgLF2bvVwxI37jgQG.JPG Sharon.JPG
website/media/856214/8xlBzvlG4TNfKgo86gM6.JPG Bill.JPG

I am using xargs -n 1 curl -O < urls.txt to download the images.

How do I download the file so ui4Q9EJoUEmVLtUNhtRX.JPG is renamed as John.JPG , 6epk0CUwnhofAjZMP2xp.JPG is renamed as Kelly.JPG etc.

Solution

  • Just reverse the order of two fields:

    while read -r url name ; do
    curl -o $name $url
done < urls.txt

    If you want concurrent download, let every curl command run in background and wait for them to finish.

    PS: -O means output file name for wget not curl. curl uses -o instead.
