[SOLVED] How to prevent Fish shell from closing when typing Ctrl-D (EOF)

Issue

I am using fish shell. When I type Ctrl-D, it sends a EOF to my terminal and then terminal closes.

I want to make it such that ctrl-D does not close my iterm2.

I saw that people have set up IGNOREEOF in bash shell like this: https://unix.stackexchange.com/questions/27588/how-can-i-keep-controld-from-disconnecting-my-session

However, I don't think this variable exists in fish. Does anybody know how I can force iterm2(with default fish shell) to not close on ctrl-D?

Solution

This is the default key binding for control-D:

bind \cd delete-or-exit

you can find this by just running bind.

(delete-or-exit is just a function, which you can read with functions delete-or-exit.)

So it's exiting because that's what the default behavior is. You can make control-D do something else. For example, maybe it should delete the character under the cursor:

bind \cd delete-char

If you want to make this permanent, add it to your fish_user_key_bindings function:

1. Run funced fish_user_key_bindings which starts editing
2. Put bind \cd delete-char within the function
3. Hit return to create the function
4. Run funcsave fish_user_key_bindings to save it
