borgmatic includes an autocompletion script for fish shell to support tab-completing command-line actions and flags. Depending on how you installed borgmatic, this may be enabled by default.

If completions aren't enabled, install the completions file globally:

borgmatic --fish-completion | sudo tee /usr/share/fish/vendor_completions.d/borgmatic.fish
source /usr/share/fish/vendor_completions.d/borgmatic.fish
