NAME
git-annex-import - import files from a special remote
SYNOPSIS
git annex import --from remote branch[:subdir] | [path ...]
DESCRIPTION
This command is a way to import a tree of files from elsewhere into your git-annex
repository. It can import files from a git-annex special remote, or from a directory.
IMPORTING FROM A SPECIAL REMOTE
Importing from a special remote first downloads or hashes all new content from it, and
then constructs a git commit that reflects files that have changed on the special remote
since the last time git-annex looked at it. Merging that commit into your repository will
update it to reflect changes made on the special remote.
This way, something can be using the special remote for file storage, adding files,
modifying files, and deleting files, and you can track those changes using git-annex.
You can combine using git annex import to fetch changes from a special remote with git
annex export to send your local changes to the special remote.
You can only import from special remotes that were configured with importtree=yes when set
up with git-annex-initremote(1). Only some kinds of special remotes will let you configure
them this way. A perhaps non-exhaustive list is the directory, s3, and adb special
remotes.
To import from a special remote, you must specify the name of a branch. A corresponding
remote tracking branch will be updated by git annex import. After that point, it's the
same as if you had run a git fetch from a regular git remote; you can merge the changes
into your currently checked out branch.
For example:
git annex import master --from myremote
git annex merge myremote/master
You could just as well use git merge myremote/master as the second step, but using git-
annex merge avoids a couple of gotchas. When using adjusted branches, it adjusts the
branch before merging from it. And it avoids the merge failing on the first merge from an
import due to unrelated histories.
If you do use git merge, you can pass --allow-unrelated-histories the first time you git
merge from an import. Think of this as the remote being a separate git repository with its
own files. If you first git annex export files to a remote, and then git annex import from
it, you won't need that option.
You can import into a subdirectory, using the "branch:subdir" syntax. For example, if
"camera" is a special remote that accesses a camera, and you want to import those into the
photos directory, rather than to the root of your repository:
git annex import master:photos --from camera
git merge camera/master
The git annex sync --content command (and the git-annex assistant) can also be used to
import from a special remote. To do this, you need to configure
"remote.<name>.annex-tracking-branch" to tell it what branch to track. For example:
git config remote.myremote.annex-tracking-branch master
git annex sync --content
Any files that are gitignored will not be included in the import, but will be left on the
remote.
When the special remote has a preferred content expression set by git-annex-wanted(1), it
will be honored when importing from it. Files that are not preferred content of the
remote will not be imported from it, but will be left on the remote.
However, preferred content expressions that relate to the key can't be matched when
importing, because the content of the file is not known. Importing will fail when such a
preferred content expression is set. This includes expressions containing "copies=",
"metadata=", and other things that depend on the key. Preferred content expressions
containing "include=", "exclude=" "smallerthan=", "largerthan=" will work.
Things in the expression like "include=" match relative to the top of the tree of files on
the remote, even when importing into a subdirectory.
OPTIONS FOR IMPORTING FROM A SPECIAL REMOTE
--content, --no-content
Controls whether annexed content is downloaded from the special remote.
The default is to download content into the git-annex repository.
With --no-content, git-annex keys are generated from information provided by the
special remote, without downloading it. Commands like git-annex get can later be
used to download files, as desired. The --no-content option is not supported by
all special remotes.
IMPORTING FROM A DIRECTORY
When run with a path, git annex import **moves** files from somewhere outside the git
working copy, and adds them to the annex. In contrast to importing from a special
directory remote, imported files are **deleted from the given path**.
This is a legacy interface. It is still supported, but please consider switching to
importing from a directory special remote instead, using the interface documented above.
Individual files to import can be specified. If a directory is specified, the entire
directory is imported. Please note that the following instruction will **delete all files
from the source directory**.
git annex import /media/camera/DCIM/*
When importing files, there's a possibility of importing a duplicate of a file that is
already known to git-annex -- its content is either present in the local repository
already, or git-annex knows of another repository that contains it, or it was present in
the annex before but has been removed now.
By default, importing a duplicate of a known file will result in a new filename being
added to the repository, so the duplicate file is present in the repository twice. (With
all checksumming backends, including the default SHA256E, only one copy of the data will
be stored.)
Several options can be used to adjust handling of duplicate files, see --duplicate,
--deduplicate, --skip-duplicates, --clean-duplicates, and --reinject-duplicates
documentation below.
OPTIONS FOR IMPORTING FROM A DIRECTORY
--duplicate
Do not delete files from the import location.
Running with this option repeatedly can import the same files into different git
repositories, or branches, or different locations in a git repository.
--deduplicate
Only import files that are not duplicates; duplicate files will be deleted from the
import location.
--skip-duplicates
Only import files that are not duplicates. Avoids deleting any files from the
import location.
--clean-duplicates
Does not import any files, but any files found in the import location that are
duplicates are deleted.
--reinject-duplicates
Imports files that are not duplicates. Files that are duplicates have their content
reinjected into the annex (similar to git-annex-reinject(1)).
--force
Allow existing files to be overwritten by newly imported files.
Also, causes .gitignore to not take effect when adding files.
file matching options
Many of the git-annex-matching-options(1) can be used to specify files to import.
git annex import /dir --include='*.png'
## COMMON OPTIONS
--jobs=N -JN
Imports multiple files in parallel. This may be faster. For example: -J4
Setting this to "cpus" will run one job per CPU core.
--no-check-gitignore
Add gitignored files.
--json Enable JSON output. This is intended to be parsed by programs that use git-annex.
Each line of output is a JSON object.
--json-progress
Include progress objects in JSON output.
--json-error-messages
Messages that would normally be output to standard error are included in the json
instead.
CAVEATS
Note that using --deduplicate or --clean-duplicates with the WORM backend does not look at
file content, but filename and mtime.
If annex.largefiles is configured, and does not match a file, git annex import will add
the non-large file directly to the git repository, instead of to the annex.
