Easily and securely share files from the command line. A [Send][send] client.

Easily and securely share files and directories from the command line through a safe, private and encrypted link using a single simple command. Files are shared using the [Send][send] service and may be up to 1GB. Others are able to download these files with this tool, or through their web browser.

All files are always encrypted on the client, and secrets are never shared with the remote host. An optional password may be specified, and a default file lifetime of 1 (up to 20) download or 24 hours is enforced to ensure your stuff does not remain online forever. This provides a secure platform to share your files. Find out more about security here.

Make sure you meet and install the requirements.

See the operating system specific instructions below:

More packages options will be coming soon.

Linux: snap package

Note: The ffsend snap package is isolated, and can only access files in your home directory. Choose a different installation option if you don't want this limitation.

Note: due to how snap is configured by default, you won't be able to use the package from some contexts such as through SSH without manual modifications. If you're experiencing problems, please refer to a different installation method such as the prebuilt binaries, or open an issue. _Note: if you want to read/write to a flash drive run snap connect ffsend:removable-media
