I know that I can download a sequence of files using decimal numbers in curl:

Just put the curl in an for iterator loop like this; save this file as some name—like test.sh and make sure that is has executable permissions—then run that file as ./test.sh:

#!/bin/bash



for i in {0..254}; do

  filename=$(printf file0x%03d.jpg $i);

  echo curl site.com/${filename} -o "${filename}";

done

The above works for me in macOS Mojave (10.14.3) as well as RedHat 7 and Ubuntu 16.04. But the following is slightly simpler, but will only work correctly on RedHat and Ubuntu; on macOS there are no padded numbers:

#!/bin/bash



for i in {000..254}; do

  curl site.com/file0x$i.jpg -o file0x$i.jpg;

done

  I think you mean file0x%03x.jpg and not file0x%03d.jpg. Otherwise the printf isn't necessary since you can generate the left-padded numbers with brace expansion using {000..254}.

  I believe the original poster made a mistake when asking about hexadecimal and truly means file0x000 to file0x254; so d is appropriate. Regarding using brace expansion using {000..254} how exactly would that work in a per number Curl call like this?
