Container scripts

Small helper scripts that ship inside every RF Swift container, and when to use each one.

Advanced · 1 min read · Updated September 27, 2026

Every RF Swift container ships a few helper scripts. Each one turns a multi-step task into a single command: starting a service, swapping a firmware, or updating the scripts themselves.

The scripts are installed in every container and are on the PATH, so you can run them from any directory inside a lab:

bash
# Example: Start Avahi service discovery
avahicontainer_start

# Example: Update RF scripts
update_rfscripts

# Example: Swap USRP firmware
libresdr_swapfpga

Available scripts

Script Command Use it to
Avahi start script avahicontainer_start Start mDNS service discovery, for example to find a PlutoSDR on the network
LibreSDR FPGA swap libresdr_swapfpga Switch a USRP B210/B220 to the LibreSDR FPGA firmware, and back
RF scripts update update_rfscripts Update the installation scripts inside a container to their latest versions
Avahi start scriptService discovery for PlutoSDR and other network devices LibreSDR FPGA swapLibreSDR firmware for USRP B210/B220, with backup and restore RF scripts updateKeep the scripts in a container up to date

If a script does not work

  • Check that the script is executable: chmod +x scriptname.
  • Check that the dependencies it needs are installed in the container.
  • Check that you have the permissions the operation needs.
  • See the troubleshooting section of the script’s own page.
