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

qrcp 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. When used to receive files, qrcp serves an upload page and handles the transfer.
The tool prints a QR code that encodes the text:
http://{address}:{port}/{random_path}
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.

qrcp MyDocument.pdfWhen sending multiple files at once, qrcp creates a zip archive of the files or folders you want to transfer, and deletes the zip archive once the transfer is complete.
# Multiple files
qrcp MyDocument.pdf IMG0001.jpg# A whole folder
qrcp Documents/You can choose to zip a file before transferring it.
qrcp --zip LongVideo.aviWhen receiving files, qrcp serves an "upload page" through which you can choose files from your mobile.
qrcp receive
# Note: the folder must exist
qrcp receive --output=/tmp/dirqrcp works without any prior configuration, however, you can choose to configure to use specific values.
To configure qrcp you can create a configuration file inside $XDG_CONFIG_HOME/qrcp.
Note: On Linux, the
$XDG_CONFIG_HOMEis.configunder user home directory. So, for example, on Linux the configuration file will be$HOME/.config/qrcp/config.yml. On MacOS, it defaults to `$HOME/Library/Application Support/qrcp/config.yml``
Note: Starting from version 0.10.0, qrcp uses a YAML configuration file instead of the old JSON one. You can automatically migrate the legacy JSON format to the new YAML format by running
qrcp config migrate.
| Key | Type | Notes |
|---|---|---|
interface |
String | This value is automatically discovered during the first launch of qrcp, you can set it to override the default. You can use the any interface to bind the web server to 0.0.0.0. |
bind |
String | This value is used by qrcp to bind the web server to. Note: if this value is set, the interface parameter is ignored. |
port |
Integer | When this value is not set, qrcp will pick a random port at any launch. |
path |
String | When this value is not set, qrcp will add a random string at the end of URL. |
output |
String | Default directory to receive files to. If empty, the current working directory is used. |
fqdn |
String | When this value is set, qrcp will use it to replace the IP address in the generated URL. |
keepAlive |
Bool | Controls whether qrcp should quit after transferring the file. Defaults to false. |
secure |
Bool | Controls whether qrcp should use HTTPS instead of HTTP. Defaults to false |
tls-cert |
String | Path to the TLS certificate. It's only used when secure: true. |
tls-key |
String | Path to the TLS key. It's only used when secure: true. |
reversed |
Bool | Reverse QR code (black text on white background)?" true`. |
All the configuration parameters can be controlled via environment variables prefixed with QRCP_, for example:
$QRCP_INTERFACE$QRCP_PORT$QRCP_KEEPALIVE- etc
The config command launches a wizard that lets you configure parameters like interface, port, fully-qualified domain name and keep alive.
qrcp configNote: if some network interfaces are not showing up, use the --list-all-interfaces flag to suppress the interfaces' filter.
qrcp --list-all-interfaces configThe default configuration file is stored in $XDG_CONFIG_HOME/qrcp/config.yml, however, you can specify the location of the config file by passing the --config flag:
qrcp --config /tmp/qrcp.yml MyDocument.pdfBy default qrcp listens on a random port. Set the QRCP_PORT environment variable or pass the --port (or -p) flag to choose a specific one:
export QRCP_PORT=8080
qrcp MyDocumentOr:
qrcp --port 8080 MyDocument.pdfqrcp will try to automatically find the suitable network interface to use for the transfers. If more than one suitable interface is found, it asks you to choose one.
If you want to use a specific interface, pass the --interface (or -i) flag:
# The webserver will be visible by
# all computers on the tun0's interface network
qrcp -i tun0 MyDocument.dpfYou can also use a special interface name, any, which binds the web server to 0.0.0.0, making the web server visible by everyone on any network, even from an external network.
This is useful when you want to transfer files from your Amazon EC2, Digital Ocean Droplet, Google Cloud Platform Compute Instance or any other VPS.
qrcp -i any MyDocument.pdfAlternatively to choosing the interface, you can directly specify the address you want qrcp to bind the webserver to.
qrcp --bind 10.20.30.40 MyDocument.pdfqrcp uses two patterns for the URLs:
- send:
http://{ip address}:{port}/send/{random path} - receive:
http://{ip address}:{port}/receive/{random path}
A few options are available that override these patterns.
Pass the --path flag to use a specific path for URLs, for example:
# The resulting URL will be
# http://{ip address}:{port}/send/x
qrcp --path=x MyDocument.pdfPass the --fqdn (or -d) to use a fully qualified domain name instead of the IP. This is useful in combination with -i any you are using it from a remote location:
# The resulting URL will be
# http://example.com:8080/send/xYz9
qrcp --fqdn example.com -i any -p 8080 MyRemoteDocument.pdfqrcp supports secure file transfers with HTTPS. To enable secure transfers you need a TLS certificate and the associated key.
You can choose the path to the TLS certificate and keys from the qrcp config wizard, or, if you want, you can pass the --tls-cert and --tls-key:
qrcp --tls-cert /path/to/cert.pem --tls-key /path/to/cert.key MyDocumentA --secure flag is available too, you can use it to override the default value.
If you need a QR to be printed outside your terminal, you can pass the --browser flag. With this flag, qrcp will still print the QR code to the terminal, but it will also open a new window of your default browser to show the QR code.
qrcp --browser MyDocument.pdf
It can be useful to keep the server alive after transferring the file, for example, when you want to transfer the same file to multiple devices. You can use the --keep-alive flag for that:
# The server will not shutdown automatically
# after the first transfer
qrcp --keep-alive MyDocument.pdfqrcp comes with a built-in completion command that generates shell completion scripts.
$ source <(qrcp completion bash)
To load completions for each session, execute once:
Linux:
$ qrcp completion bash > /etc/bash_completion.d/qrcp
Note: if you don't want to install completion scripts system-wide, refer to Bash Completion FAQ.
MacOS:
$ qrcp completion bash > /usr/local/etc/bash_completion.d/qrcp
If shell completion is not already enabled in your environment you will need to enable it. You can execute the following once:
$ echo "autoload -U compinit; compinit" >> ~/.zshrc
To load completions for each session, execute once:
$ qrcp completion zsh > "${fpath[1]}/_qrcp"
You will need to start a new shell for this setup to take effect.
$ qrcp completion fish | source
To load completions for each session, execute once:
$ qrcp completion fish > ~/.config/fish/completions/qrcp.fish
qrcp, originally called qr-filetransfer, started from an idea of Claudio d'Angelis (@claudiodangelis on Telegram), the current maintainer, and it's developed by the community.
