When downloading a file using curl, how would I follow a link location and use that for the output filename (without knowing the remote filename in advance)?
For example, if one clicks on the link below, you would download a filenamed "pythoncomplete.vim." However using curl's -O and -L options, the filename is simply the original remote-name, a clumsy "download_script.php?src_id=10872."
curl -O -L http://www.vim.org/scripts/download_script.php?src_id=10872
In order to download the file with the correct filename you would have to know the name of the file in advance:
curl -o pythoncomplete.vim -L http://www.vim.org/scripts/download_script.php?src_id=10872
It would be excellent if you could download the file without knowing the name in advance, and if not, is there another way to quickly pull down a redirected file via command line?
The remote side sends the filename using the Content-Disposition header.
curl 7.21.2 or newer does this automatically if you specify --remote-header-name / -J.
curl -O -J -L $url
The expanded version of the arguments would be:
curl --remote-name --remote-header-name --location $url
