# HowTo Use _source_ on a Synology As the Synology DSM uses _sh_ as default shell instead of e.g. the _bash_ it refuses if you want to `source .env` your ssh environment for example while updating a docker setup. As easy as it is I could just open a bash with `bash` in the ssh. There I could again use the usual `source .env` command. Maybe I could change the default shell to bash while ssh-ing?
