Download Ticket Service – dl is now on fedora.

From :

“dl” is a file exchange service that allows you to upload any file to a web server and generate a unique ticket for others to download. The ticket is automatically expired according to the specified rules, so that you don’t need to keep track or cleanup afterward. “dl” also allows you to grant an anonymous, one-time upload for others to send you a file, without the requirement of account management.

“dl” can directly be integrated into Thunderbird (see DL for Thunderbird), also includes two native clients (see dl-wx, or watch the introduction) that allow to use the service directly from the shell for maximum convenience, without opening a browser!

“dl” is usually installed as a “email attachments replacement” due to its simplicity (though can be used in other ways).

To install on Fedora:

sudo yum install dl
