gc is a command-line tool to sync activities, workouts, and so on to the Garmin Connect service. It is NOT an official tool. It mainly targets the Linux as Garmin doesn't provide the Connect Launcher for this platform.

git clone https://github.com/phacops/gc.git
cd gc
go install

gc will try to locate a configuration file at

${XDG_CONFIG_HOME}/gc/config
${HOME}/.config/gcrc
${HOME/.gcrc

It should be a valid json file. Valid keys are gc_username, gc_password, and watch_dir. The first two variables are Garmin Connect credentials, the last one is where the Garmin device is mounted. If some of these variables are not set, the user will be prompted to type them.

Example:

{
  "gc_username":"[email protected]",
  "gc_password":"aVeryComplexPassword",
  "watch_dir":"/mnt"
}

gc supports syncing activities, workouts, and download updated EPO file. The Garmin device must first be mounted.

Without config file:

$ gc sync activities
Garmin Connect Username: [email protected]
Garmin Connect Password: 
Watch Mount Directory: /mnt
syncing ACTIVITY1.FIT... success

If you saved your settings in a config file, then no prompt is issued:

$ gc sync activities
syncing ACTIVITY3.FIT... success

Username and watch mount directory can be overriden with the --username, -u and --dir, -d options respectively.

You can get more info using the built-in help:

$ gc --help
$ gc sync --help
