{date_utc} encodes the post creation date in UTC rather than the
current local timezone, as {date} does.
This was proposed in #69. Encoding the post creation date in
local time zone induces problems regarding --fast-update when the
time zone is changed.

|
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`),
|
|
|
|
``@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,
|
|
|
|
- :option:`--metadata-json`, to store further post metadata in a separate JSON
|
|
file.
|
|
|
|
.. _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. The default is ``--filename-pattern={date}``.
|
|
The tokens ``{target}`` and ``{profile}`` are replaced like in the
|
|
dirname pattern. Further, the tokens ``{date}``, ``{date_utc}`` and ``{shortcode}`` are
|
|
defined. Additionally, in case of not downloading stories, the attributes of
|
|
:class:`.Post` can be used, e.g. ``{post.owner_id}`` or ``{post.mediaid}``.
|
|
|
|
For example, encode the poster's profile name in the filenames with:
|
|
|
|
::
|
|
|
|
instaloader --filename-pattern={date}_{profile} "#hashtag"
|
|
|
|
The pattern string is formatted with Python's string formatter. This
|
|
gives additional flexibilty for pattern specification. For example,
|
|
`strftime-style formatting options <https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior>`__
|
|
are supported for the post's
|
|
timestamp. The default for ``{date}`` is ``{date:%Y-%m-%d_%H-%M-%S}``.
|
|
|
|
.. _filter-posts:
|
|
|
|
Filter Posts
|
|
^^^^^^^^^^^^
|
|
|
|
The :option:`--only-if` option allows to specify criterias that posts have to
|
|
meet to be downloaded. If not given, all posts are downloaded. It must be a
|
|
boolean Python expression where the variables :attr:`.likes`, :attr:`.comments`,
|
|
:attr:`.viewer_has_liked`, :attr:`.is_video`, and many more are defined.
|
|
|
|
A few examples:
|
|
|
|
To **download the pictures from your feed that you have liked**:
|
|
|
|
::
|
|
|
|
instaloader --login=your_username --only-if=viewer_has_liked :feed
|
|
|
|
Or you might only want to download **posts that either you liked or were
|
|
liked by many others**:
|
|
|
|
::
|
|
|
|
instaloader --login=your_username --only-if="likes>100 or viewer_has_liked" profile
|
|
|
|
Or you may **skip videos**:
|
|
|
|
::
|
|
|
|
instaloader --only-if="not is_video" target
|
|
|
|
Or you may filter by hashtags that occur in the Post's caption. For
|
|
example, to download posts of kittens that are cute: ::
|
|
|
|
instaloader --only-if="'cute' in caption_hashtags" "#kitten"
|
|
|
|
The given string is evaluated as a
|
|
`Python boolean expression <https://docs.python.org/3/reference/expressions.html#boolean-operations>`__,
|
|
where all occuring variables are attributes of the :class:`.Post` class.
