nix develop shell incomplete PATH contents about nix HOT 3 OPEN

This could possibly be worked around with this ugly hack:

nix develop -c bash -ec 'exec fish'

from nix.

Nix develop runs bash, not fish.
Perhaps your .bashrc contains a fish invocation. And I suspect it also messes with your $PATH as well. Try to start debugging from there.

@xzfc, you are right, but everything it do is:

# If not running interactively, don't do anything
[ ! -z "$PS1" ]          || return
[ ! -z "$IN_NIX_SHELL" ] || source /etc/profile

[ ! -z "$IN_NIX_SHELL" ] || exec fish

PS1='[\u@\h \W]\$ '

But even if I remove .bashrc nothing changes. So I think the problem is in something different.
I have fish shell specified as a main shell in /etc/passwd:

λ  grep /home/user /etc/passwd                                                                                      
user:x:1000:100::/home/user:/nix/store/vmzchllkdmf08786vg63kjdz5vnwh8bf-fish-3.7.1/bin/fish

So... event without mentioned .bashrc I will end up inside fish after running nix develop.
