|
|
Basic Usage
|
|
^^^^^^^^^^^
|
|
|
|
To **download all pictures and videos of a profile**, as well as the
|
|
**profile picture**, do
|
|
|
|
::
|
|
|
|
instaloader profile [profile ...]
|
|
|
|
where ``profile`` is the name of a profile you want to download. Instead
|
|
of only one profile, you may also specify a list of profiles.
|
|
|
|
To later **update your local copy** of that profiles, you may run
|
|
|
|
::
|
|
|
|
instaloader --fast-update profile [profile ...]
|
|
|
|
If :option:`--fast-update` is given, Instaloader stops when arriving at the
|
|
first already-downloaded picture. When updating profiles, Instaloader
|
|
automatically **detects profile name changes** and renames the target directory
|
|
accordingly.
|
|
|
|
Instaloader can also be used to **download private profiles**. To do so,
|
|
invoke it with
|
|
|
|
::
|
|
|
|
instaloader --login=your_username profile [profile ...]
|
|
|
|
When logging in, Instaloader **stores the session cookies** in a file in your
|
|
temporary directory, which will be reused later the next time :option:`--login`
|
|
is given. So you can download private profiles **non-interactively** when you
|
|
already have a valid session cookie file.
|
|
|
|
.. _what-to-download:
|
|
|
|
What to Download
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
Instaloader supports the following targets:
|
|
|
|
``profile``
|
|
Public profile, or private profile with :option:`--login`. For each profile
|
|
you download, :option:`--stories` instructs Instaloader to also
|
|
**download the user's stories**.
|
|
|
|
``"#hashtag"``
|
|
Posts with a certain **hashtag** (the quotes are usually neccessary),
|
|
|
|
``:stories``
|
|
The currently-visible **stories** of your followees (requires
|
|
:option:`--login`),
|
|
|
|
``:feed``
|
|
Your **feed** (requires :option:`--login`),
|
|
|
|
``:saved``
|
|
Posts which are marked as **saved** (requires :option:`--login`),
|
|
|
|
``@profile``
|
|
All profiles that are followed by ``profile``, i.e. the *followees* of
|
|
``profile`` (requires :option:`--login`).
|
|
|
|
Instaloader goes through all media matching the specified targets and
|
|
downloads the pictures and videos and their captions. You can specify
|
|
|
|
- :option:`--comments`, to also **download comments** of each post,
|
|
|
|
- :option:`--geotags`, to **download geotags** of each post and save them as
|
|
Google Maps link,
|
|
|
|
.. _filename-specification:
|
|
|
|
Filename Specification
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
For each target, Instaloader creates a directory named after the target,
|
|
i.e. ``profile``, ``#hashtag``, ``:feed``, etc. and therein saves the
|
|
posts in files named after the post's timestamp.
|
|
|
|
:option:`--dirname-pattern` allows to configure the directory name of each
|
|
target. The default is ``--dirname-pattern={target}``. In the dirname
|
|
pattern, the token ``{target}`` is replaced by the target name, and
|
|
``{profile}`` is replaced by the owner of the post which is downloaded.
|
|
|
|
:option:`--filename-pattern` configures the path of the post's files relative
|
|
to the target directory that is specified with :option:`--dirname-pattern`.
|
|
The default is ``--filename-pattern={date_utc}_UTC``.
|
|
The tokens ``{target}`` and ``{profile}`` are replaced like in the
|
|
dirname pattern. The following tokens are defined for usage with
|
|
:option:`--filename-pattern`:
|
|
|
|
- ``{target}``
|
|
Target name (as given in Instaloader command line)
|
|
|
|
- ``{profile}`` (same as ``{owner_username}``)
|
|
Owner of the Post / StoryItem.
|
|
|
|
- ``{owner_id}``
|
|
Unique integer ID of owner profile.
|
|
|
|
- ``{shortcode}``
|
|
Shortcode (identifier string).
|
|
|
|
- ``{mediaid}``
|
|
Integer representation of shortcode.
|
|
|
|
- ``{date_utc}`` (same as ``{date}``)
|
|
Creation time in UTC timezone.
|
|
`strftime()-style formatting options <https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior>`__
|
|
are supported as format specifier. The default date format specifier used by
|
|
Instaloader is::
|
|
|
|
{date_utc:%Y-%m-%d_%H-%M-%S}
|
|
|
|
For example, encode the poster's profile name in the filenames with::
|
|
|
|
instaloader --filename-pattern={date_utc}_UTC_{profile} "#hashtag"
|
|
|
|
As another example, you may instruct Instaloader to store posts in a
|
|
``PROFILE/YEAR/SHORTCODE.jpg`` directory structure::
|
|
|
|
instaloader --dirname-pattern={profile} --filename-pattern={date_utc:%Y}/{shortcode} <target> ...
|
|
|
|
.. _filter-posts:
|
|
|
|
Filter Posts
|
|
^^^^^^^^^^^^
|
|
|
|
.. py:currentmodule:: instaloader
|
|
|
|
The options :option:`--post-filter` and :option:`--storyitem-filter`
|
|
allows to specify criterias that posts or story items have to
|
|
meet to be downloaded. If not given, all posts are downloaded.
|
|
|
|
The filter string must be a
|
|
`Python boolean expression <https://docs.python.org/3/reference/expressions.html#boolean-operations>`__
|
|
where the attributes from :class:`Post` or
|
|
:class:`StoryItem` respectively are defined.
|
|
|
|
Id est, the following attributes can be used with both
|
|
:option:`--post-filter` and :option:`--storyitem-filter`:
|
|
|
|
- :attr:`~Post.is_video` (bool)
|
|
Post/StoryItem is a video. For example, you may skip videos::
|
|
|
|
instaloader --post-filter="not is_video" target
|
|
|
|
- :attr:`~Post.owner_username` (str), :attr:`~Post.owner_id` (int)
|
|
Owner profile username / userid.
|
|
|
|
- :attr:`~Post.date_utc` (datetime), :attr:`~Post.date_local` (datetime)
|
|
Creation timestamp. Since :class:`~datetime.datetime` objects can be created
|
|
inside filter strings, this easily allows filtering by creation date. E.g.::
|
|
|
|
instaloader --post-filter="date_utc <= datetime(2018, 5, 31)" target
|
|
|
|
As :option:`--post-filter`, the following attributes can be used additionally:
|
|
|
|
- :attr:`~Post.viewer_has_liked` (bool)
|
|
Whether user (with :option:`--login`) has liked given post. To download the
|
|
pictures from your feed that you have liked::
|
|
|
|
instaloader --login=your_username --post-filter=viewer_has_liked :feed
|
|
|
|
- :attr:`~Post.likes` (int), :attr:`~Post.comments` (int)
|
|
Likes count / Comments count. You might only want to download posts that
|
|
either you liked or were liked by many others**::
|
|
|
|
instaloader --login=your_username --post-filter="likes>100 or viewer_has_liked" profile
|
|
|
|
- :attr:`~Post.caption_hashtags` (list of str) / :attr:`~Post.caption_mentions` (list of str)
|
|
``#hashtags`` or ``@mentions`` (lowercased) in the Post's caption. For example, to
|
|
download posts of kittens that are cute::
|
|
|
|
instaloader --post-filter="'cute' in caption_hashtags" "#kitten"
|
|
|
|
- :attr:`~Post.tagged_users` (list of str)
|
|
Lowercased usernames that are tagged in the Post.
|
|
|
|
For :option:`--storyitem-filter`, the following additional attributes are
|
|
defined:
|
|
|
|
- :attr:`~StoryItem.expiring_utc` (datetime) / :attr:`~StoryItem.expiring_local` (datetime)
|
|
Timestamp when StoryItem will get unavailable.
