[docs]@parser(Specs.lsinitrd) class Lsinitrd(CommandParser): """ A parser for command "lsinitrd". Attributes: data (dict): The key is the filename, the value is a dict describe the file's info. unparsed_lines(list): List of strings for unparsed lines. As this lsinitrd spec is set to filterable, the structure of the output is broken. Hence, this parser will parse only filelisting like lines in output of 'lisinitrd', and also store all the unparsed lines. If the other parts of the output structure are required in the future, an enhancement may be performed then. Examples: >>> len( 5 >>> assert'kernel') == [ ... {'group': 'root', 'name': 'kernel/x86', 'links': 3, 'perms': 'rwxr-xr-x', ... 'raw_entry': 'drwxr-xr-x 3 root root 0 Apr 20 15:58 kernel/x86', ... 'owner': 'root', 'date': 'Apr 20 15:58', 'type': 'd', 'dir': '', 'size': 0} ... ] >>> "udev-rules" in ls.unparsed_lines True """
