True
>>> len(output.target_startswith('/run/netns')) == 3
True
>>> output.target_startswith('/run/netns')[0].get('propagation', None) == 'shared'
True

cols

List of key value pair derived from the command.

Type:

list

keywords

keywords(or TARGETs) present in the command

Type:

list

parse_content(content)

This method must be implemented by classes based on this class.

search_target(target)

Similar to __contains__() but returns the list of targets.

Example

>>> output.search_target('shm') == [{'target': '/dev/shm', 'source': 'tmpfs', 'fstype': 'tmpfs', 'options': 'rw,nosuid,nodev,seclabel', 'propagation': 'shared'}]
True

target_startswith(target)

Return all the targets that starts with ‘target’. Useful to find the mountpoints.

Example

>>> len(output.target_startswith('/run/netns')) == 3
True
