How to change the default shell to fish?

[moritz1000]

Hello,

I am running Arch Linux and using Fish as an interactive shell exclusively in my terminal emulators. Fish is not set as my system shell.

I recently installed Ghossty and looked at the Ghossty documentation. However, I couldn't find an obvious way to configure Ghossty to use Fish as the shell.

The "Shell Integration" section mentioned in the documentation doesn't seem to address what I'm looking for in this case.

On Alacritty I can do this via alacritty.toml:

[terminal]
[terminal.shell]
program = "/usr/bin/fish"

On Konsole via the GUI:

On kitty via kitty.conf:

shell /usr/bin/fish

---

How can I configure Ghossty to use Fish as the shell?
Thank you for your help!

~/.config/ghostty/config:
command = /usr/local/bin/fish --login --interactive

I am doing this on macOS but It's causing all of my shells can't detect binaries in PATH correctly. For example my fish shell can't detect starship and fastfetch. Is there anything I can do to fix this? I installed fish using homebrew and added the following line to my configuration file.

command = /opt/homebrew/bin/fish

Below is the error. The second image shows the issue after I added the command configuration.

Apple silicon? You need to add /opt/homebrew/bin/brew shellenv | source to the beginning of config.fish.

@zzhaolei Thank you!

I think this feature deserves more prominent documentation and should not be burried in https://ghostty.org/docs/config/reference#command since everyone who is using a different interactive shell requires this information.

At least it would be friendlier for beginners - especially since the documentation has no search function.

As a reminder for people like me:

to reload the config you must properly quit (e.g. ⌘Q) Ghostty and open it again. Just closing all terminal windows does not stop the program.

Using reload config Command + Shift + , keyboard shortcut also work. You don't need to quit the terminal. At least it works for me.
