git-annex - manage files with git, without checking their contents in


git annex command [params ...]


git-annex allows managing files with git, without checking the file contents into git.
While that may seem paradoxical, it is useful when dealing with files larger than git can
currently easily handle, whether due to limitations in memory, checksumming time, or disk

Even without file content tracking, being able to manage files with git, move files around
and delete files with versioned directory trees, and use branches and distributed clones,
are all very handy reasons to use git. And annexed files can co-exist in the same git
repository with regularly versioned files, which is convenient for maintaining documents,
Makefiles, etc that are associated with annexed files but that benefit from full revision

When a file is annexed, its content is moved into a key-value store, and a symlink is made
that points to the content. These symlinks are checked into git and versioned like regular
files. You can move them around, delete them, and so on. Pushing to another git repository
will make git-annex there aware of the annexed file, and it can be used to retrieve its
content from the key-value store.

Like many git commands, git-annex can be passed a path that is either a file or a
directory. In the latter case it acts on all relevant files in the directory. When no path
is specified, most git-annex commands default to acting on all relevant files in the
current directory (and subdirectories).

help Display built-in help.

a good complement to git fsck.

See git-annex-fsck(1) for details.

expire [repository:]time ...
Expires repositories that have not recently performed an activity (such as a fsck).

past locations of files.

See git-annex-forget(1) for details.

repair This can repair many of the problems with git repositories that git fsck detects,
but does not itself fix. It's useful if a repository has become badly damaged. One
way this can happen is if a repository used by git-annex is on a removable drive
that gets unplugged at the wrong time.

See git-annex-repair(1) for details.


find [path ...]

Outputs a list of annexed files in the specified path. With no path, finds files in
the current directory and its subdirectories.

See git-annex-find(1) for details.

whereis [path ...]
Displays information about where the contents of files are located.

See git-annex-whereis(1) for details.

list [path ...]
Displays a table of remotes that contain the contents of the specified files. This
is similar to whereis but a more compact display.

See git-annex-list(1) for details.

log [path ...]
Displays the location log for the specified file or files, showing each repository
they were added to ("+") and removed from ("-").

See git-annex-log(1) for details.

info [directory|file|remote|uuid ...]
Displays statistics and other information for the specified item, which can be a
directory, or a file, or a remote, or the uuid of a repository.

When no item is specified, displays statistics and information for the repository
as a whole.

See git-annex-info(1) for details.

Shows the version of git-annex, as well as repository version information.

See git-annex-version(1) for details.

map Generate map of repositories.

See git-annex-map(1) for details.


metadata [path ...]

The content of an annexed file can have any number of metadata fields attached to
it to describe it. Each metadata field can in turn have any number of values.

This command can be used to set metadata, or show the currently set metadata.

See git-annex-metadata(1) for details.

view [tag ...] [field=value ...] [field=glob ...] [!tag ...] [field!=value ...]
Uses metadata to build a view branch of the files in the current branch, and checks
out the view branch. Only files in the current branch whose metadata matches all
the specified field values and tags will be shown in the view.

See git-annex-view(1) for details.

vpop [N]
Switches from the currently active view back to the previous view. Or, from the
first view back to original branch.

See git-annex-vpop(1) for details.

vfilter [tag ...] [field=value ...] [!tag ...] [field!=value ...]
Filters the current view to only the files that have the specified field values and

See git-annex-vfilter(1) for details.

vadd [field=glob ...] [field=value ...] [tag ...]
Changes the current view, adding an additional level of directories to categorize
the files.

See git-annex-vfilter(1) for details.

vcycle When a view involves nested subdirectories, this cycles the order.

See git-annex-vcycle(1) for details.


migrate [path ...]

Changes the specified annexed files to use a different key-value backend.

See git-annex-migrate(1) for details.

reinject src dest
Moves the src file into the annex as the content of the dest file. This can be
useful if you have obtained the content of a file from elsewhere and want to put it
in the local annex.

See git-annex-reinject(1) for details.

unannex [path ...]
Use this to undo an accidental git annex add command. It puts the file back how it
was before the add.

See git-annex-unannex(1) for details.

uninit De-initialize git-annex and clean out repository.

See git-annex-uninit(1) for details.

reinit uuid|description
Initialize repository, reusing old UUID.

See git-annex-reinit(1) for details.


pre-commit [path ...]

This is meant to be called from git's pre-commit hook. git annex init automatically
creates a pre-commit hook using this.

See git-annex-pre-commit(1) for details.

lookupkey [file ...]
Looks up key used for file.

See git-annex-lookupkey(1) for details.

contentlocation [key ..]
Looks up location of annexed content for a key.

Drops annexed content for specified keys.

See git-annex-dropkey(1) for details.

transferkey key [--from=remote|--to=remote]
Transfers a key from or to a remote.

See git-annex-transferkey(1) for details.

Used internally by the assistant.

See git-annex-transferkey(1) for details.

setpresentkey key uuid [1|0]
This plumbing-level command changes git-annex's records about whether the specified
key's content is present in a remote with the specified uuid.

See git-annex-setpresentkey(1) for details.

readpresentkey key uuid
Read records of where key is present.

See git-annex-readpresentkey(1) for details.

checkpresentkey key remote
Check if key is present in remote.

See git-annex-checkpresentkey(1) for details.

rekey [file key ...]
Change keys used for files.

See git-annex-rekey(1) for details.

findref [ref]
Lists files in a git ref.

See git-annex-findref(1) for details.

proxy -- git cmd [options]
Only useful in a direct mode repository, this runs the specified git command with a
temporary work tree, and updates the working tree to reflect any changes staged or
committed by the git command.

See git-annex-proxy(1) for details.

Resolves a conflicted merge, by adding both conflicting versions of the file to the
tree, using variants of their filename. This is done automatically when using git
annex sync or git annex merge.

See git-annex-resolvemerge(1) for details.

This can be used to make git diff use an external diff driver with annexed files.

See git-annex-diffdriver(1) for details.

Detects when network remotes have received git pushes and fetches from them.

See git-annex-remotedaemon(1) for details.

This command is used internally by the assistant to perform git pulls over XMPP.

See git-annex-xmppgit(1) for details.



This runs git-annex's built-in test suite.

See git-annex-test(1) for details.

testremote remote
This tests a remote by generating some random objects and sending them to the
remote, then redownloading them, removing them from the remote, etc.

It's safe to run in an existing repository (the repository contents are not
altered), although it may perform expensive data transfers.

See git-annex-testremote(1) for details.

Generates random changes to files in the current repository, for use in testing the

See git-annex-fuzztest(1) for details.


These common options are accepted by all git-annex commands, and may not be explicitly
listed on their individual man pages. (Many commands also accept the git-

Force unsafe actions, such as dropping a file's content when no other source of it
can be verified to still exist, or adding ignored files. Use with care.

--fast Enable less expensive, but also less thorough versions of some commands. What is
avoided depends on the command.

Avoid the default verbose display of what is done; only show errors.

Enable verbose display.

Show debug messages.

Disable debug messages.

Overrides the numcopies setting, forcing git-annex to ensure the specified number
of copies exist.

Note that setting numcopies to 0 is very unsafe.

Limits how long a git-annex command runs. The time can be something like "5h", or
"30m" or even "45s" or "10d".

Note that git-annex may continue running a little past the specified time limit, in
order to finish processing a file.

Also, note that if the time limit prevents git-annex from doing all it was asked
to, it will exit with a special code, 101.



Overrides trust settings for a repository. May be specified more than once.

The repository should be specified using the name of a configured remote, or the
UUID or description of a repository.

Amazon Glacier inventories take hours to retrieve, and may not represent the
current state of a repository. So git-annex does not trust that files that the
inventory claims are in Glacier are really there. This switch can be used to allow
it to trust the inventory.

Be careful using this, especially if you or someone else might have recently
removed a file from Glacier. If you try to drop the only other copy of the file,
and this switch is enabled, you could lose data!

Specifies which key-value backend to use. This can be used when adding a file to
the annex, or migrating a file. Once files are in the annex, their backend is known
and this option is not necessary.

Overrides the User-Agent to use when downloading files from the web.

Caused a desktop notification to be displayed after each successful file download
and upload.

(Only supported on some platforms, e.g. Linux with dbus. A no-op when not

Caused a desktop notification to be displayed when a file upload or download has
started, or when a file is dropped.

-c name=value
Overrides git configuration settings. May be specified multiple times.


Like other git commands, git-annex is configured via .git/config. Here are all the
supported configuration settings.

A unique UUID for this repository (automatically set).

Space-separated list of names of the key-value backends to use. The first listed
is used to store new files by default.

Amount of disk space to reserve. Disk space is checked when transferring content to
avoid running out, and additional free space can be reserved via this option, to
make space for more important content (such as git commit logs). Can be specified
with any commonly used units, for example, "0.5 gb", "500M", or "100 KiloBytes"

The default reserve is 1 megabyte.

Allows configuring which files are considered to be large enough to need to be
added to the annex. By default, all specified files are added to the annex, but
configuring this can cause the small files to be checked into git, without using
the annex.

The value is a preferred content expression. See git-annex-preferred-content(1) for


annex.largefiles = largerthan=100kb and not (include=*.c or include=*.h)

This setting is checked by git annex add, git annex import and the assistant. It's
also used by git annex addurl and git annex importfeed when downloading files.

It can be useful to temporarily override it via -c at the command line. For

git annex add -c annex.largefiles='include=*' 99kbfile

This is a deprecated setting. You should instead use the git annex numcopies
command to configure how many copies of files are kept across all repositories.

This config setting is only looked at when git annex numcopies has never been

Note that setting numcopies to 0 is very unsafe.

Set this to true to make git-annex automatically generate some metadata when adding
files to the repository.

In particular, it stores year and month metadata, from the file's modification

When importfeed is used, it stores additional metadata from the feed, such as the
author, title, etc.

This controls which refs git-annex unused considers to be used. See REFSPEC FORMAT
in git-annex-unused(1) for details.

git-annex builds a queue of git commands, in order to combine similar commands for
speed. By default the size of the queue is limited to 10240 commands; this can be
used to change the size. If you have plenty of memory and are working with very
large numbers of files, increasing the queue size can speed it up.

The git annex unused and git annex sync --content commands use a bloom filter to
determine what files are present in eg, the work tree. The default bloom filter is
sized to handle up to 500000 files. If your repository is larger than that, you
should increase this value. Larger values will make git-annex unused and git annex
sync --content consume more memory; run git annex info for memory usage numbers.

Adjusts the accuracy of the bloom filter used by git annex unused and git annex
sync --content. The default accuracy is 10000000 -- 1 unused file out of 10000000
will be missed by git annex unused. Increasing the accuracy will make git annex
unused consume more memory; run git annex info for memory usage numbers.

By default, git-annex caches ssh connections using ssh's ControlMaster and
ControlPersist settings (if built using a new enough ssh). To disable this, set to

By default, git-annex automatically commits data to the git-annex branch after each
command is run. If you have a series of commands that you want to make a single
commit, you can run the commands with -c annex.alwayscommit=false. You can later
commit the data by running git annex merge (or by automatic merges) or git annex

Note that you beware running git gc if using this configuration, since it could
garbage collect objects that are staged in git-annex's index but not yet committed.

Set this to true to make file contents be hard linked between the repository and
its remotes when possible, instead of a more expensive copy.

Use with caution -- This can invalidate numcopies counting, since with hard links,
fewer copies of a file can exist. So, it is a good idea to mark a repository using
this setting as untrusted.

When a repository is set up using git clone --shared, git-annex init will
automatically set annex.hardlink and mark the repository as untrusted.

Makes the watch and assistant commands delay for the specified number of seconds
before adding a newly created file to the annex. Normally this is not needed,
because they already wait for all writers of the file to close it. On Mac OSX, when
not using direct mode this defaults to 1 second, to work around a bad interaction
with software there.

Controls what the assistant does about unused file contents that are stored in the

The default is false, which causes all old and unused file contents to be retained,
unless the assistant is able to move them to some other repository (such as a
backup repository).

Can be set to a time specification, like "7d" or "1m", and then file contents that
have been known to be unused for a week or a month will be deleted.

When set to false, prevents the webapp from reminding you when using repositories
that lack consistency checks.

When set to ask (the default), the webapp will check for new versions and prompt if
they should be upgraded to. When set to true, automatically upgrades without
prompting (on some supported platforms). When set to false, disables any upgrade

Note that upgrade checking is only done when git-annex is installed from one of the
prebuilt images from its website. This does not bypass e.g., a Linux distribution's
own upgrade handling code.

This setting also controls whether to restart the git-annex assistant when the git-
annex binary is detected to have changed. That is useful no matter how you
installed git-annex.

Set to false to prevent the git-annex assistant and git-annex sync from
automatically committing changes to files in the repository.

Set to false to prevent the git-annex assistant from scanning the repository for
new and changed files on startup. This will prevent it from noticing changes that
were made while it was not running, but can be a useful performance tweak for a
large repository.

Configures which address the webapp listens on. The default is localhost. Can be
either an IP address, or a hostname that resolves to the desired address.

Set to true to enable debug logging by default.

Automatically maintained, and used to automate upgrades between versions.

Set to true when the repository is in direct mode. Should not be set manually; use
the "git annex direct" and "git annex indirect" commands instead.

Set to true if the repository is on a crippled filesystem, such as FAT, which does
not support symbolic links, or hard links, or unix permissions. This is
automatically probed by "git annex init".

Normally, git-annex uses fine-grained lock files to allow multiple processes to run
concurrently without getting in each others' way. That works great, unless you are
using git-annex on a filesystem that does not support POSIX fcntl locks. This is
sometimes the case when using NFS or Lustre filesystems.

To support such situations, you can set annex.pidlock to true, and it will fall
back to a single top-level pid file lock.

Although, often, you'd really be better off fixing your networked filesystem
configuration to support POSIX locks.. And, some networked filesystems are so
inconsistent that one node can't reliably tell when the other node is holding a pid
lock. Caveat emptor.

When using pid lock files, it's possible for a stale lock file to get left behind
by previous run of git-annex that crashed or was interrupted. This is mostly
avoided, but can occur especially when using a network file system.

git-annex will wait up to this many seconds for the pid lock file to go away, and
will then abort if it cannot continue. Default: 300

When determining which repository to transfer annexed files from or to, ones with
lower costs are preferred. The default cost is 100 for local repositories, and 200
for remote repositories.

If set, the command is run, and the number it outputs is used as the cost. This
allows varying the cost based on e.g., the current network. The cost-command can be
any shell command line.

A command to run when git-annex begins to use the remote. This can be used to, for
example, mount the directory containing the remote.

The command may be run repeatedly when multiple git-annex processes are running

A command to run when git-annex is done using the remote.

The command will only be run once *all* running git-annex processes are finished
using the remote.

Specify an alternative git-annex-shell executable on the remote instead of looking
for "git-annex-shell" on the PATH.

This is useful if the git-annex-shell program is outside the PATH or has a
non-standard name.

If set to true, prevents git-annex from storing file contents on this remote by
default. (You can still request it be used by the --from and --to options.)

This is, for example, useful if the remote is located somewhere without git-
annex-shell. (For example, if it's on GitHub). Or, it could be used if the network
connection between two repositories is too slow to be used normally.

This does not prevent git-annex sync (or the git-annex assistant) from syncing the
git repository to the remote.

If set to false, prevents git-annex sync (and the git-annex assistant) from syncing
with this remote.

If set to true, prevents git-annex from making changes to a remote. This both
prevents git-annex sync from pushing changes, and prevents storing or removing
files from read-only remote.

remote.<name>.annex-verify, annex.verify
By default, git-annex will verify the checksums of objects downloaded from remotes.
If you trust a remote and don't want the overhead of these checksums, you can set
this to false.

Can be used to specify a different url than the regular remote.<name>.url for git-
annex to use when talking with the remote. Similar to the pushUrl used by git-push.

git-annex caches UUIDs of remote repositories here.

Configures a local trust level for the remote. This overrides the value configured
by the trust and untrust commands. The value can be any of "trusted", "semitrusted"
or "untrusted".

Can be used to tell git-annex whether a remote is LocallyAvailable or
GloballyAvailable. Normally, git-annex determines this automatically.

Can be used to tell git-annex if a remote is a bare repository or not. Normally,
git-annex determines this automatically.

Options to use when using ssh to talk to this remote.

Options to use when using rsync to or from this remote. For example, to force IPv6,
and limit the bandwidth to 100Kbyte/s, set it to -6 --bwlimit 100

Options to use when using rsync to upload a file to a remote.

These options are passed after other applicable rsync options, so can be used to
override them. For example, to limit upload bandwidth to 10Kbyte/s, set --bwlimit

Options to use when using rsync to download a file from a remote.

These options are passed after other applicable rsync options, so can be used to
override them.

The remote shell to use to connect to the rsync remote. Possible values are ssh
(the default) and rsh, together with their arguments, for instance ssh -p 2222 -c
blowfish; Note that the remote hostname should not appear there, see rsync(1) for
details. When the transport used is ssh, connections are automatically cached
unless annex.sshcaching is unset.

Options to pass to bup split when storing content in this remote. For example, to
limit the bandwidth to 100Kbyte/s, set it to --bwlimit 100k (There is no
corresponding option for bup join.)

Options to pass to GnuPG for symmetric encryption. For instance, to use the AES
cipher with a 256 bits key and disable compression, set it to --cipher-algo AES256
--compress-algo none. (These options take precedence over the default GnuPG
configuration, which is otherwise used.)

Default options to use if a remote does not have more specific options as described

Options to pass when running wget or curl. For example, to force IPv4 only, set it
to "-4"

Options to pass to quvi when using it to find the url to download for a video.

Options to pass to aria2c when using it to download a torrent.

HTTP headers to send when downloading from the web. Multiple lines of this option
can be set, one per header.

If set, the command is run and each line of its output is used as a HTTP header.
This overrides annex.http-headers.

Use to specify a command to run to download a file from the web. (The default is
to use wget or curl.)

In the command line, %url is replaced with the url to download, and %file is
replaced with the file that it should be saved to.

This can be set to a command that should be run whenever git-annex removes the
content of a file from the repository.

In the command line, %file is replaced with the file that should be erased.

For example, to use the wipe command, set it to wipe -f %file.

Used by rsync special remotes, this configures the location of the rsync repository
to use. Normally this is automatically set up by git annex initremote, but you can
change it if needed.

Used by bup special remotes, this configures the location of the bup repository to
use. Normally this is automatically set up by git annex initremote, but you can
change it if needed.

Used by ddar special remotes, this configures the location of the ddar repository
to use. Normally this is automatically set up by git annex initremote, but you can
change it if needed.

Used by directory special remotes, this configures the location of the directory
where annexed files are stored for this remote. Normally this is automatically set
up by git annex initremote, but you can change it if needed.

Used to identify Amazon S3 special remotes. Normally this is automatically set up
by git annex initremote.

Used to identify Amazon Glacier special remotes. Normally this is automatically
set up by git annex initremote.

Used to identify webdav special remotes. Normally this is automatically set up by
git annex initremote.

Used to identify tahoe special remotes. Points to the configuration directory for

Used to identify the XMPP address of a Jabber buddy. Normally this is set up by
the git-annex assistant when pairing over XMPP.

Used to identify gcrypt special remotes. Normally this is automatically set up by
git annex initremote.

It is set to "true" if this is a gcrypt remote. If the gcrypt remote is accessible
over ssh and has git-annex-shell available to manage it, it's set to "shell".

remote.<name>.hooktype, remote.<name>.externaltype
Used by hook special remotes and external special remotes to record the type of the

annex.tune.objecthash1, annex.tune.objecthashlower, annex.tune.branchhash1
These can be passed to git annex init to tune the repository. They cannot be
safely changed in a running repository. For details, see <http://git-

CONFIGURATION VIA .gitattributes

The key-value backend used when adding a new file to the annex can be configured on a
per-file-type basis via .gitattributes files. In the file, the annex.backend attribute can
be set to the name of the backend to use. For example, this here's how to use the WORM
backend by default, but the SHA256E backend for ogg files:

* annex.backend=WORM
*.ogg annex.backend=SHA256E

The numcopies setting can also be configured on a per-file-type basis via the
annex.numcopies attribute in .gitattributes files. This overrides other numcopies
settings. For example, this makes two copies be needed for wav files and 3 copies for
flac files:

*.wav annex.numcopies=2
*.flac annex.numcopies=3

Note that setting numcopies to 0 is very unsafe.

These settings are honored by git-annex whenever it's operating on a matching file.
However, when using --all, --unused, or --key to specify keys to operate on, git-annex is
operating on keys and not files, so will not honor the settings from .gitattributes.

Also note that when using views, only the toplevel .gitattributes file is preserved in the
view, so other settings in other files won't have any effect.


git-annex, when called as a git subcommand, may return exit codes 0 or 1 for success or
failures, or, more rarely, 127 or 128 for certain very specific failures. git-annex
itself should return 0 on success and 1 on failure, unless the --time-limit=time option is
hit, in which case it returns with exit code 101.
