--value-stdin, or read a .env file with --file. Hoista never prints a value back.
hoist env list [PROJECT]
List a project’s variable names. Values are never shown.
hoist env set [PROJECT] [NAMES]...
Set variables. Values are typed hidden, piped, or read from a .env file; never in arguments.
On a project Hoista manages, the new values go out in a new deploy, so the release and its values change together; retry with the same
--request-key and values. On a watched project they’re set at the provider, which redeploys it unless you pass --no-redeploy.
