This replaces the use of bash where suitable, to allow easier copy/pasting
of shell examples without copying the prompt or process output.

## Description
|
|
|
|
The `docker pause` command suspends all processes in the specified containers.
|
|
On Linux, this uses the freezer cgroup. Traditionally, when suspending a process
|
|
the `SIGSTOP` signal is used, which is observable by the process being suspended.
|
|
With the freezer cgroup the process is unaware, and unable to capture,
|
|
that it is being suspended, and subsequently resumed. On Windows, only Hyper-V
|
|
containers can be paused.
|
|
|
|
See the
|
|
[freezer cgroup documentation](https://www.kernel.org/doc/Documentation/cgroup-v1/freezer-subsystem.txt)
|
|
for further details.
