Does Fish shell cache the locations of previously-run commands?

Question

I know in Bash and similar shells, there is the hash command, which gets run when the user runs a non-builtin command, and cleared when (for example) you update $PATH or run hash -r.

And I know that the Fish shell includes the history command, which also gets updated when you run a command and cleared when running history clear. But the purpose of the history command doesn't seem to be to cache paths to command files, as with Bash's bash command. I'm basing this on the contents of my local ~/.local/share/fish/fish_history file, which seems to include the commands and the timestamps they were run, but no absolute paths to command files:

- cmd: history
  when: 1697724735
- cmd: exit
  when: 1697724738
- cmd: history clear --help
- cmd: cat ~/.local/share/fish/fish_history
  when: 1697805134
  paths:
    - ~/.local/share/fish/fish_history

So my question is- does Fish have a similar command cache to Bash?

Answer 1

No, there is no command cache in fish, and so no need for a hash command. $PATH is searched for every external command.
