How do you "source" a file in fish?

Question

I'd like to use keychain with the fish shell, but I'm not sure how to get fish to load the ~/.keychain/hostname-fish file to set the appropriate environment variables.

In bash, there's the "source" command, but it doesn't exist in fish.

Answer 1

Below is what I have in ~/.config/fish/config.fish for your specific example.

set -gx HOSTNAME (hostname)
if status --is-interactive;
    keychain --nogui --clear ~/.ssh/id_rsa
    [ -e $HOME/.keychain/$HOSTNAME-fish ]; and source $HOME/.keychain/$HOSTNAME-fish
end

The source command is source, which also works in bash.

Prior to fish 2.1.0, the source command was called ..

Answer 2

Use the source command:

source filename.txt

source may not have existed originally but it exists now and the . alias in fish is officially deprecated.

From man . in fish 3.6.1:

. (a single period) is an alias for the source command. The use of . is deprecated in favour of source, and . will be removed in a future version of fish.

Answer 3

If the file you're trying to source contains bash, consider using Bass.

This will let you write, for example:

bass source ~/.bash_profile

Answer 4

The way recommended on the Keychain documentation page is to put this in config.fish:

if status --is-interactive
    keychain --eval --quiet --quick path/to/id_rsa
end

Then, add this to the top of your script:

source $HOME/.keychain/(hostname)-fish

Answer 5

The problem is usually you're using source with something that contains bash in it so instead I:

bash
source whatever.sh
