ssh_common_args:
description: Common extra args for all ssh CLI tools

ssh_executable:
default: ssh
description:
- This defines the location of the ssh binary. It defaults to `ssh` which will use the first ssh binary available in $PATH.
- This option is usually not required, it might be useful when access to system ssh is restricted,
or when using ssh wrappers to connect to remote hosts.

- name: ANSIBLE_REMOTE_USER
vars:
- name: ansible_user

pipelining:
default: ANSIBLE_PIPELINING
description:
- Pipelining reduces the number of SSH operations required to execute a module on the remote server,
by executing many Ansible modules without actual file transfer.
- This can result in a very significant performance improvement when enabled.
- However this conflicts with privilege escalation (become).
For example, when using sudo operations you must first disable 'requiretty' in the sudoers file for the target hosts,
which is why this feature is disabled by default.

control_path:
default: null
description:
- This is the location to save ssh's ControlPath sockets, it uses ssh's variable substitution.
- Since 2.3, if null, ansible will generate a unique hash. Use `%(directory)s` to indicate where to use the control dir path setting.

ini:
- key: control_path

control_path_dir:
default: ~/.ansible/cp
description:
- This sets the directory to use for ssh control path if the control path setting is null.
- Also, provides the `%(directory)s` variable for the control path setting.

description:
