|
||||
The following flags can be given to Instaloader to specify how profiles should
|
||||
be downloaded.
|
||||
|
||||
--fast-update Stop when encountering the first already-downloaded post
|
||||
of a profile.
|
||||
--profile-pic-only Only download profile pictures. Without this flag, the current
|
||||
profile picture and all the profile's posts are downloaded.
|
||||
--skip-videos Skip posts which are videos.
|
||||
--geotags Also **download geotags** and store Google Maps links in
|
||||
separate textfiles.
|
||||
--count COUNT If used with ``#hashtag``, ``:feed-all`` or
|
||||
``:feed-liked``: Do not attempt to download more than COUNT
|
||||
posts.
|
||||
--quiet Do not output any messages except warnings and errors. This
|
||||
option makes Instaloader **suitable as a cron job**.
|
||||
--no-sleep Normally, Instaloader waits a few seconds between requests
|
||||
to the Instagram servers. This flag inhibits this behavior.
|
||||
--password PASSWORD If used with ``--login``, use parameter as password if no
|
||||
valid session file is found, instead of asking
|
||||
interactively.
|
||||
--sessionfile FILE Specify an alternative place for loading and storing the
|
||||
session cookies. Without this flag, they are stored in a path
|
||||
within your temporary directory, encoding your local
|
||||
username and your instagram profile name.
|
||||
--no-profile-subdir Instead of creating a subdirectory for each profile and
|
||||
storing pictures there, store pictures in files named
|
||||
'PROFILE__DATE_TIME.jpg.'
|
||||
--hashtag-username When downloading by #hashtag, lookup the picture's username
|
||||
to decide in which directory to store, rather than storing
|
||||
all pictures in directory '#hashtag'.
|
||||
--user-agent STRING Change User Agent for HTTP requests to STRING, rather than
|
||||
our default user agent (Chrome 51).
|
||||
To get a list of all flags, their abbreviations and their descriptions, you may
|
||||
run ``instaloader --help``.
|
||||
|
||||
To get a list of all flags, run ``instaloader --help``.
|
||||
What to Download
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
Specify a list of profiles or #hashtags. For each of these, Instaloader
|
||||
downloads all posts along with the pictures's captions and the current
|
||||
**profile picture**.
|
||||
|
||||
--profile-pic-only Only download profile picture.
|
||||
--skip-videos Do not download videos.
|
||||
--geotags **Download geotags** when available. Geotags are stored as
|
||||
a text file with the location's name and a Google Maps
|
||||
link. This requires an additional request to the
|
||||
Instagram server for each picture, which is why it is
|
||||
disabled by default.
|
||||
|
||||
When to Stop Downloading
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If none of these options are given, Instaloader goes through all pictures
|
||||
matching the specified targets.
|
||||
|
||||
--fast-update For each target, stop when encountering the first
|
||||
already-downloaded picture. This flag is recommended
|
||||
when you use Instaloader to update your personal
|
||||
Instagram archive.
|
||||
--count COUNT Do not attempt to download more than COUNT posts.
|
||||
Applies only to ``#hashtag``, ``:feed-all`` and ``:feed-liked``.
|
||||
|
||||
|
||||
Login (Download Private Profiles)
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Instaloader can **login to Instagram**. This allows downloading private
|
||||
profiles and automatically **finding profiles by their ID** if they have been
|
||||
renamed. To login, pass the ``--login`` option. Your session cookie (not your
|
||||
password!) will be saved to a local file to be reused next time you want
|
||||
Instaloader to login.
|
||||
|
||||
--login YOUR-USERNAME Login name (profile name) for your Instagram account.
|
||||
--sessionfile SESSIONFILE Path for loading and storing session key file.
|
||||
Defaults to a path
|
||||
within your temporary directory, encoding your local
|
||||
username and your Instagram profile name.
|
||||
--password YOUR-PASSWORD Password for your Instagram account. Without this
|
||||
option, you'll be prompted for your password
|
||||
interactively if there is not yet a valid session
|
||||
file.
|
||||
|
||||
How to Download
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
--no-profile-subdir Instead of creating a subdirectory for each profile
|
||||
and storing pictures there, store pictures in files
|
||||
named ``PROFILE__DATE_TIME.jpg``.
|
||||
--hashtag-username Lookup username of pictures when downloading by
|
||||
#hashtag and encode it in the downlaoded file's path
|
||||
or filename (if ``--no-profile-subdir``). Without this
|
||||
option, the #hashtag is used instead. This requires an
|
||||
additional request to the Instagram server for each
|
||||
picture, which is why it is disabled by default.
|
||||
--user-agent USER_AGENT User Agent to use for HTTP requests. Per default,
|
||||
Instaloader pretends being Chrome/51.
|
||||
--no-sleep Do not sleep between requests to Instagram's servers.
|
||||
This makes downloading faster, but may be suspicious.
|
||||
|
||||
Miscellaneous Options
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
--shorter-output Do not display captions while downloading.
|
||||
--quiet Disable user interaction, i.e. do not print messages
|
||||
(except errors) and fail if login credentials are
|
||||
needed but not given. This makes Instaloader
|
||||
**suitable as a cron job**.
