What is transfer.sh?

Transfer.sh is a tool that lets you share files directly from your computer's command line. Instead of opening a browser, navigating to a file-sharing website, and clicking through upload buttons, you type a single command and get back a web link that anyone can use to download your file. You can also set files to automatically expire after a certain number of downloads or days, and there's built-in support for encrypting files before they leave your machine. Under the hood, this is server software that you host yourself. When someone uploads a file, the server stores it and generates a unique download link. The project doesn't lock you into one storage solution, it can save files to your local server, Amazon S3, Google Drive, or Storj. It also includes security features like IP whitelisting, password protection for uploads, file size limits, and integration with ClamAV to scan for viruses. The files can be set to purge automatically after a set number of days. The people who would get the most out of this are developers, system administrators, or technical teams who frequently share log files, screenshots, or data dumps and want a faster workflow than using a browser. For example, a developer troubleshooting a bug could pipe an error log straight from their terminal to a shareable link, or a team could set up a private file-sharing service on their own infrastructure rather than relying on public tools they don't control. One important note from the project: the public website running this software at transfersh.com has been flagged as malware, so you should not use that site. The value here is in downloading and running the software on your own server, where you control the storage, the security settings, and who has access. The project is written in Go and ships with a Docker container for straightforward deployment, which means a technical team can get an instance running with minimal setup.
