Ctrl+S in fish shell does not work as in bash

Question

Ctrl+S and Ctrl+Q can be used to pause/resume output in bash shell. But in fish shell, it does not work. Are there any replacement?

Answer 1

This is intentional. Fish disables terminal flow control because the original developers concluded the feature causes too many problems for inexperienced CLI users especially those used to emacs where [ctrl-s] is normally bound to the incremental search function and thus might type it at a shell prompt.

Answer 2

On the upside, the same functionality can be added to your fish shell with a function and a key-binding.

See the following plugins, for example:

• https://github.com/oh-my-fish/plugin-bang-bang (implements the !! variant)
