# Why are the session variables not set? {#_why_are_the_session_variables_not_set}

Home Manager is only able to set session variables automatically if it
|
||
|
|
manages your Bash, Z shell, or fish shell configuration. To enable such
|
||
|
|
management you use [programs.bash.enable](#opt-programs.bash.enable),
|
||
|
|
[programs.zsh.enable](#opt-programs.zsh.enable), or [programs.fish.enable](#opt-programs.fish.enable).
|
||
|
|
|
||
|
|
If you don't want to let Home Manager manage your shell then you will
|
||
|
|
have to manually source the
|
||
|
|
`~/.nix-profile/etc/profile.d/hm-session-vars.sh` file in an appropriate
|
||
|
|
way. In Bash and Z shell this can be done by adding
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
. "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh"
|
||
|
|
```
|
||
|
|
|
||
|
|
to your `.profile` and `.zshrc` files, respectively. The
|
||
|
|
`hm-session-vars.sh` file should work in most Bourne-like shells. For
|
||
|
|
fish shell, it is possible to source it using [the foreign-env
|
||
|
|
plugin](https://github.com/oh-my-fish/plugin-foreign-env)
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
fenv source "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh" > /dev/null
|
||
|
|
```
