Lsinitrd - command lsinitrd

This parser parses the filtered output of command lsinitrd and provides the info of listed files.

class insights.parsers.lsinitrd.Lsinitrd(context, extra_bad_lines=None)[source]

Bases: insights.core.CommandParser

A parser for command “lsinitrd”.

data

The key is the filename, the value is a dict describe the file’s info.

Type

dict

unparsed_lines

List of strings for unparsed lines.

Type

list

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(ls.data)
5
>>> assert ls.search(name__contains='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
parse_content(content)[source]

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

search(**kwargs)[source]

Search the listed files for matching rows based on key-value pairs.

This uses the insights.parsers.keyword_search() function for searching; see its documentation for usage details. If no search parameters are given, no rows are returned.

Returns

A list of dictionaries of files that match the given search criteria.

Return type

list

Examples

>>> lsdev = ls.search(name__contains='dev')
>>> len(lsdev)
3
>>> dev_console = {
...     'type': 'c', 'perms': 'rw-r--r--', 'links': 1, 'owner': 'root', 'group': 'root',
...     'major': 5, 'minor': 1, 'date': 'Apr 20 15:57', 'name': 'dev/console', 'dir': '',
...     'raw_entry': 'crw-r--r--   1 root     root       5,   1 Apr 20 15:57 dev/console'
... }
>>> dev_console in lsdev
True
>>> 'dev/kmsg' in [l['name'] for l in lsdev]
True
>>> 'dev/null' in [l['name'] for l in lsdev]
True
