Default shell for bitbucket pipeline

Help me understand which default shell is used in Bitbucket pipelines.


We defines Docker images with `step.image` and several steps in `script`.


Healthy conclusion is that each `script` line is sent to shell, defiled by Docket image which can vary.


I see that `.` / `source` operator is working for sh like-shells. That mean each `script` command reuses same sh session.


Is it correct that there is no predefined shell executors?

Is it correct that each line of step executed within same shell session?

Each step runs in a separate docker container.

How the container behaves, and which shell it uses depends on the docker image used. Each line of script inside a step executes in the same shell session.


I hope that helps!
