So I have gotten a link to an image from google

https://media.istockphoto.com/photos/pile-of-euro-notes-picture-id471843075?k=20&m=471843075&s=612x612&w=0&h=aEFb1spFMtvSnsNvkpgA2tULw-cmcBC4nwbCvDFYN9c=

I got this by right clicking on the image and getting the URL address of the image

This is another Image url I got in the same way

https://m.media-amazon.com/images/I/61RzcieEZpL._AC_SX522_.jpg

Both images show up fine when I paste the links in the browser

When I use curl to download the second image it does so without issues

curl -O 'https://m.media-amazon.com/images/I/61RzcieEZpL._AC_SX522_.jpg'

However, for the second...

curl -O 'https://media.istockphoto.com/photos/pile-of-euro-notes-picture-id471843075?k=20&m=471843075&s=612x612&w=0&h=aEFb1spFMtvSnsNvkpgA2tULw-cmcBC4nwbCvDFYN9c='

The downloaded file is just this strange looking text file

Can anyone tell me why this is happening?

CodePudding user response：

Your viewer just failed to fathom out that the file is a JPEG image because it has the wrong extension. Try adding an extension like this:

curl -O 'https://media.istockphoto.com/photos/pile-of-euro-notes-picture-id471843075?k=20&m=471843075&s=612x612&w=0&h=aEFb1spFMtvSnsNvkpgA2tULw-cmcBC4nwbCvDFYN9c=' > image.jpg

If you might be downloading PNGs and GIFs and stuff other than JPEG, you can use file to get a sensible extension:

curl ... > UnknownThing

Then:

file -b --extension UnknownThing
jpeg/jpg/jpe/jfif

So maybe something along the lines of:

curl ... > UnknownThing
ext=$(file -b  --extension UnknownThing | sed 's|/.*||')
mv UnknownThing image.${ext}
