Create alias in Fish shell and save this as a permanent.

Create a Permanent Alias in Fish Shell

Method 1

In Fish, an alias is actually implemented as a function. To make it permanent, you need to save the function using funcsave.

alias foo=bar
funcsave foo

This creates the file ~/.config/fish/functions/foo.fish, making the alias available in all future Fish sessions.

Method 2

I prefer this method because it allows me to manage all my aliases in a single file.

1. Open ~/.config/fish/config.fish in your favorite editor. If the file doesn't exist yet, create it.
2. Add the aliases you want to use.
3. Save the file.
4. Reload the configuration:

source ~/.config/fish/config.fish

Since config.fish is loaded whenever Fish starts, your aliases will be available in every new shell session.

Enjoy!

Tip

If the alias doesn't work immediately, run source ~/.config/fish/config.fish or open a new terminal window to reload your Fish configuration.

Thanks a lot, man, I was going crazy trying to find it. I’m a beginner, so this might be obvious, but once you’ve written the command using the second method, you have to close the terminal and reopen it. I couldn't figure out why it wasn't working for me, and then I found the reason.

You're welcome!

Just as a small note, you don't actually need to close and reopen the terminal. After editing ~/.config/fish/config.fish, you can reload the configuration with:

source ~/.config/fish/config.fish

That will apply the changes immediately to your current Fish session. Reopening the terminal works too, since Fish automatically loads config.fish when it starts.
