NAME
git-annex - manage files with git, without checking their contents in
SYNOPSIS
git annex command [params ...]
DESCRIPTION
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 space.
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 control.
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.
EXAMPLES
# git annex get video/hackity_hack_and_kaxxt.mov
get video/hackity_hack_and_kaxxt.mov (not available)
I was unable to access these remotes: server
Try making some of these repositories available:
5863d8c0-d9a9-11df-adb2-af51e6559a49 -- my home file server
58d84e8a-d9ae-11df-a1aa-ab9aa8c00826 -- portable USB drive

COMMONLY USED COMMANDS
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.
For help on a specific command, use git annex help command

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

prints a numbered list of the data.
See git-annex-unused(1) for details.
dropunused [number|range ...]
Drops the data corresponding to the numbers, as listed by the last git annex unused
See git-annex-dropunused(1) for details.
addunused [number|range ...]
Adds back files for the content corresponding to the numbers or ranges, as listed by the last git
annex unused.
See git-annex-addunused(1) for details.
fix [path ...]

forget Causes the git-annex branch to be rewritten, throwing away historical data about 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.
QUERY COMMANDS
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.
version
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 COMMANDS
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 tags.
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.
UTILITY COMMANDS
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.
PLUMBING COMMANDS
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.
See git-annex-contentlocation(1) for details.

Print information that can be determined purely by looking at the key.
See git-annex-examinekey(1) for details.
fromkey [key file]
Manually set up a file in the git repository to link to a specified key.
See git-annex-fromkey(1) for details.
registerurl [key url]
Registers an url for a key.
See git-annex-registerurl(1) for details.
setkey key file
Moves a file into the annex as the content of a key.
See git-annex-setkey(1) for details.
dropkey [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.
transferkeys
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.
resolvemerge
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.
diffdriver
This can be used to make git diff use an external diff driver with annexed files.
See git-annex-diffdriver(1) for details.
remotedaemon
Detects when network remotes have received git pushes and fetches from them.
See git-annex-remotedaemon(1) for details.
xmppgit
This command is used internally by the assistant to perform git pulls over XMPP.
See git-annex-xmppgit(1) for details.
TESTING COMMANDS
test
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.
fuzztest
Generates random changes to files in the current repository, for use in testing the assistant.
See git-annex-fuzztest(1) for details.
COMMON OPTIONS
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-annex-matching-options(1).)
--force
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.
--quiet
Avoid the default verbose display of what is done; only show errors.
--verbose
Enable verbose display.
--debug
Show debug messages.
--no-debug
Disable debug messages.
--numcopies=n
Overrides the numcopies setting, forcing git-annex to ensure the specified number of copies exist.
Note that setting numcopies to 0 is very unsafe.
--time-limit=time
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.
--trust=repository
--semitrust=repository
--untrust=repository
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.
--trust-glacier-inventory
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!
--backend=name
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.
--user-agent=value
Overrides the User-Agent to use when downloading files from the web.
--notify-finish
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 supported.)
--notify-start
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.
CONFIGURATION VIA .git/config
Like other git commands, git-annex is configured via .git/config. Here are all the supported
configuration settings.
annex.uuid
A unique UUID for this repository (automatically set).
annex.backends
Space-separated list of names of the key-value backends to use. The first listed is used to store
new files by default.
annex.diskreserve
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.
annex.largefiles
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 details.
Example:
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 example:
git annex add -c annex.largefiles='include=*' 99kbfile
annex.numcopies
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 configured.
Note that setting numcopies to 0 is very unsafe.
annex.genmetadata
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 date.
When importfeed is used, it stores additional metadata from the feed, such as the author, title,
etc.
annex.used-refspec
This controls which refs git-annex unused considers to be used. See REFSPEC FORMAT in git-
annex-unused(1) for details.
annex.queuesize
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.
annex.bloomcapacity
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.
annex.bloomaccuracy
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.
annex.sshcaching
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 false.
annex.alwayscommit
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 sync.
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.
annex.hardlink
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.
annex.delayadd
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.
annex.expireunused
Controls what the assistant does about unused file contents that are stored in the repository.
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.
annex.fscknudge
When set to false, prevents the webapp from reminding you when using repositories that lack
consistency checks.
annex.autoupgrade
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 checking.
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.
annex.autocommit
Set to false to prevent the git-annex assistant and git-annex sync from automatically committing
changes to files in the repository.
annex.startupscan
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.
annex.listen
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.
annex.debug
Set to true to enable debug logging by default.
annex.version
Automatically maintained, and used to automate upgrades between versions.
annex.direct
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.
annex.crippledfilesystem
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".
annex.pidlock
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.
annex.pidlocktimeout
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
remote.<name>.annex-cost
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.
remote.<name>.annex-cost-command
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.
remote.<name>.annex-start-command
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 concurrently.
remote.<name>.annex-stop-command
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.
remote.<name>.annex-shell
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.
remote.<name>.annex-ignore
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.
remote.<name>.annex-sync
If set to false, prevents git-annex sync (and the git-annex assistant) from syncing with this
remote.
remote.<name>.annex-readonly
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.
remote.<name>.annexUrl
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.
remote.<name>.annex-uuid
git-annex caches UUIDs of remote repositories here.
remote.<name>.annex-trustlevel
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".
remote.<name>.annex-availability
Can be used to tell git-annex whether a remote is LocallyAvailable or GloballyAvailable. Normally,
git-annex determines this automatically.
remote.<name>.annex-bare
Can be used to tell git-annex if a remote is a bare repository or not. Normally, git-annex
determines this automatically.
remote.<name>.annex-ssh-options
Options to use when using ssh to talk to this remote.
remote.<name>.annex-rsync-options
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
remote.<name>.annex-rsync-upload-options
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 10.
remote.<name>.annex-rsync-download-options
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.
remote.<name>.annex-rsync-transport
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.
remote.<name>.annex-bup-split-options
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.)
remote.<name>.annex-gnupg-options
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.)
annex.ssh-options, annex.rsync-options,
annex.rsync-upload-options, annex.rsync-download-options, annex.bup-split-options,
annex.gnupg-options
Default options to use if a remote does not have more specific options as described above.
annex.web-options
Options to pass when running wget or curl. For example, to force IPv4 only, set it to "-4"
annex.quvi-options
Options to pass to quvi when using it to find the url to download for a video.
annex.aria-torrent-options
Options to pass to aria2c when using it to download a torrent.
annex.http-headers
HTTP headers to send when downloading from the web. Multiple lines of this option can be set, one
per header.
annex.http-headers-command
If set, the command is run and each line of its output is used as a HTTP header. This overrides
annex.http-headers.
annex.web-download-command
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.
annex.secure-erase-command
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.
remote.<name>.rsyncurl
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.
remote.<name>.buprepo
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.
remote.<name>.ddarrepo
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.
remote.<name>.directory
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.
remote.<name>.s3
Used to identify Amazon S3 special remotes. Normally this is automatically set up by git annex
initremote.
remote.<name>.glacier
Used to identify Amazon Glacier special remotes. Normally this is automatically set up by git
annex initremote.
remote.<name>.webdav
Used to identify webdav special remotes. Normally this is automatically set up by git annex
initremote.
remote.<name>.tahoe
Used to identify tahoe special remotes. Points to the configuration directory for tahoe.
remote.<name>.annex-xmppaddress
Used to identify the XMPP address of a Jabber buddy. Normally this is set up by the git-annex
assistant when pairing over XMPP.
remote.<name>.gcrypt
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 remote.
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-annex.branchable.com/tuning/>.
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.
EXIT STATUS
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.
FILES
These files are used by git-annex:
.git/annex/objects/ in your git repository contains the annexed file contents that are currently
available. Annexed files in your git repository symlink to that content.
.git/annex/ in your git repository contains other run-time information used by git-annex.
~/.config/git-annex/autostart is a list of git repositories to start the git-annex assistant in.
.git/hooks/pre-commit-annex in your git repository will be run whenever a commit is made to the HEAD
branch, either by git commit, git-annex sync, or the git-annex assistant.
.git/hooks/post-update-annex in your git repository will be run whenever the git-annex branch is updated.
You can make this hook run git update-server-info when publishing a git-annex repository by http.
