fah-beta-mgr

fah-beta-mgr is a bash script which manages FAH beta binaries, so you don't have to. It assumes that it's running in a systemd-flavored Linux distro. Here's what it does:

• Maintains an A/B setup of fah-client binaries, which can be switched between at any time
  • So if a new beta is problematic, a single command will restart FAH with the previous version
• Checks for new beta releases of fah-client
• If one exists, it is downloaded and becomes the new 'A' fah-client binary
  • And previous 'A' binary becomes the new 'B' binary
  • Unless the 'B' binary was active, in which case it is retained
• The script can self-update, upon request

Absolutely not guaranteed to be bug-free, but my publishing toolchain requires a clean pass of shellcheck before updating this site. Made available under the MIT license

Getting started

• Download the script here
• Or give it a read first, if you like
• As root, run /path/to/fah-beta-mgr setup
  • This will move the script to /usr/local/bin and do other setup tasks
• Run fah-beta-mgr update to fetch the current beta FAH client and make it the active binary
  • Repeat this whenever you want to check for a new beta
• See fah-beta-mgr help and/or the rest of this document, for more options
