'''Setting fish as default for Gnome Console''' | |||
It is possible to set fish as the interactive non-login shell for Gnome Console without setting fish as the login shell (the login shell in /etc/passwd for your user will not be fish). | |||
{{File|3=home-manager.users.myuser = { | |||
dconf = { | |||
enable = true; | |||
settings."org/gnome/console" = { | |||
shell = [ "FISH" ]; | |||
}; | |||
}; | |||
};|name=home.nix|lang=nix}} | |||
If you still want to set fish as the login shell, see [[Command Shell#Changing the default shell]]. | If you still want to set fish as the login shell, see [[Command Shell#Changing the default shell]]. | ||
