Simplify a bit (and possibly speed it up a little) the parsing of the output of `subscription-manager repos --list`: - simplify skipping the lines that are not interesting: check the first character only, as it is enough to determine whether it contains repository data or not - check the start of each line manually, rather than with regexp: a simple slice + lstrip() gives the same result

short_description: Manage RHSM repositories using the subscription-manager command
|
|
description:
|
|
- Manage (Enable/Disable) RHSM repositories to the Red Hat Subscription
|
|
Management entitlement platform using the C(subscription-manager) command.
|
|
author: Giovanni Sciortino (@giovannisciortino)
|
|
notes:
|
|
- In order to manage RHSM repositories the system must be already registered
|
|
to RHSM manually or using the Ansible M(community.general.redhat_subscription) module.
|
|
- It is possible to interact with C(subscription-manager) only as root,
|
|
so root permissions are required to successfully run this module.

|
