|
||
|
|
For some, this is a nice shell-agnostic way of setting environment variables and could replace setting through shell profiles (i.e., <code class="inline-verbatim">.bashrc</code>, <code class="inline-verbatim">.profile</code>).
|
||
|
|
</p><p>It needs a <code class="inline-verbatim">*.conf</code> file in one of the load paths (seen from the <code class="inline-verbatim">environment.d.5</code> manual page).
|
||
|
|
Just like how <a href="/wiki/linux.systemd#systemd-at-user-level">systemd at user-level</a>, you can set it at user-level by placing them in certain user-level load paths (e.g., <code class="inline-verbatim">$XDG_CONFIG_HOME/environment.d</code>).
|
||
|
|
</p><p>Keep in mind it does not use the shell directly and instead makes use of shell-like syntax.
|
||
|
|
The syntax takes variable substitutions and parameter expansion seen from <a href="id:dd9d3ffa-03ff-42a1-8c5d-55dc9fcc70fe">GNU Bash</a>.
|
||
|
|
</p><p>The following code block is an example of setting Nix-related environment variables to enable desktop integrations.
|
||
|
|
</p><pre class="src-block"><code class="language-ini"># Enable desktop integration with Nix-installed applications.

NIX_PATH=$HOME/.nix-defexpr/channels${NIX_PATH:+:}$NIX_PATH
