qr-filetransfer

Transfer files over Wi-Fi from your computer to a mobile device by scanning a QR code without leaving the terminal.

Install

go get github.com/claudiodangelis/qr-filetransfer

Installation through a package manager

AUR (Arch Linux)

How does it work?

This tool binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete.

The tool prints a QR code that encodes the text:

http://{address}:{port}

Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser.

Usage

Note: Both the computer and device must be on the same Wi-Fi network.

On its first run, qr-filetransfer will ask you to choose which network interface you want to use to transfer the files. Choose the network interface that is connected to your Wi-Fi:

$ qr-filetransfer /tmp/file
Choose the network interface to use (type the number):
[0] enp3s0
[1] wlp0s20u10

Note: On Linux it usually starts with wl.

The chosen network will be saved and no more setup is necessary, unless you pass the -force argument, or delete the .qr-filetransfer.json file that the program stores in the home directory of current user.

Transfer a single file

qr-filetransfer /path/to/file.txt

Zip the file, then transfer it

qr-filetransfer -zip /path/to/file.txt

Transfer a full directory. Note: the directory gets zipped before being transferred

qr-filetransfer /path/to/directory

Arguments

• -debug increases verbosity
• -force ignores saved configuration
• -zip zips the content before transferring it
