qr-filetransfer

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

Install

go get github.com/claudiodangelis/qr-filetransfer

How does it work?

This tool binds a web server to the address of your wifi network interface on a random port, and sets a default handler for it. The default handler serves the content and quits the program when the transfer is complete.

The program 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 URL with the default browser), so when QR the code is scanned the content starts being downloaded by the mobile browser.

Usage

Screenshot

Note: Both computer and device must be on the same wifi 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 wifi:

$ 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 choice will be remembered and you will never be prompted again, 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 transfered

qr-filetransfer /path/to/directory

Arguments

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