# astro env variable link

<Info>
  This command is only available on Astro.
</Info>

Use `astro env variable link` commands to manage the per-Deployment links of a Workspace-scoped environment variable. A link attaches a Workspace variable to a specific Deployment and can carry a per-Deployment value override. You can also exclude a Deployment from a variable that automatically links to every Deployment in the Workspace. Identify the variable with either `--variable-id` or `--variable-key`.
