Some packages provide the shell integration to be more useful. But unlike other systems, nix doesn't have a standard share directory location. This is why a bunch PACKAGE-share scripts are shipped that print the location of the corresponding shared folder. Current list of such packages is as following: fzf: fzf-share E.g. fzf can then used in the .bashrc like this: source "$(fzf-share)/completion.bash" source "$(fzf-share)/key-bindings.bash"
