[Q] A way to rehash `$commands` values?

[noboruma]

Describe your question
Is there a way to rehash the $commands values?
The ftb-tmux-popup script was failing because $commands[fzf] (here) was pointing to an old fzf path on my system.
Is there a way to refresh it?

Restart the shell will reset it automatically. Or you can use hash -r command.
