How do I save a file using the response header filename with cURL?

Question

This question relates to the command line version of cURL.

I\'m trying to download a file from a CGI script.

http://example.com/perl/dl.pl?ID=2


        

Answer 1

you can try the -o or -O option.

Answer 2

if you have a new enough curl (version 7.20.0 or later), -J/--remote-header-name is what you want.

You use -J in conjunction with -O, which makes curl use the file name part from the URL as its primary way to name the output file and then if there is a Content-disposition: header in the response, curl will use that name instead.

Answer 3

curl -OJ gave me segmentation fault: 11 error when attempting to download multiple URLs at once.

Instead, I used wget. The latest version supports HTTP Content-Disposition headers, which often contain filename information.

wget --content-disposition http://example.com/download/url

Answer 4

curl http://example.com/dl.php?file=3123123 -O -J

if server uses redirection use these:

--location-trusted
--max-redirs 10
