## Reading a `.env` file { #reading-a-env-file }

If you have many settings that possibly change a lot, maybe in different environments, it might be useful to put them on a file and then read them from it as if they were environment variables.

This practice is common enough that it has a name, these environment variables are commonly placed in a file `.env`, and the file is called a "dotenv".

// There are some caveats regarding the following:
// 1. object lock config - object lock should have been specified at time of bucket creation. Only default retention settings are imported here.
// 2. Replication config - is omitted from import as remote target credentials are not available from exported data for security reasons.
// 3. lifecycle config - if transition rules are present, tier name needs to have been defined.
