.TH git-annex 1
.SH NAME
git\-annex \- manage files with git, without checking their contents in
.PP
.SH SYNOPSIS
git annex command [params ...]
.PP
.SH 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.
.PP
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.
.PP
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.

Generates random changes to files in the current repository,
for use in testing the assistant.
.IP
See git\-annex\-fuzztest(1) for details.
.IP
.SH 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).)
.PP
.IP "\fB\-\-force\fP"
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.
.IP
.IP "\fB\-\-fast\fP"
Enable less expensive, but also less thorough versions of some commands.
What is avoided depends on the command.
.IP
.IP "\fB\-\-quiet\fP"
Avoid the default verbose display of what is done; only show errors
and progress displays.
.IP
.IP "\fB\-\-verbose\fP"
Enable verbose display.
.IP
.IP "\fB\-\-debug\fP"
Show debug messages.
.IP
.IP "\fB\-\-no\-debug\fP"
Disable debug messages.
.IP
.IP "\fB\-\-numcopies=n\fP"
Overrides the numcopies setting, forcing git\-annex to ensure the
specified number of copies exist.
.IP
Note that setting numcopies to 0 is very unsafe.
.IP
.IP "\fB\-\-time\-limit=time\fP"
Limits how long a git\-annex command runs. The time can be something
like "5h", or "30m" or even "45s" or "10d".
.IP
Note that git\-annex may continue running a little past the specified
time limit, in order to finish processing a file.
.IP
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.
.IP
.IP "\fB\-\-trust=repository\fP"
.IP "\fB\-\-semitrust=repository\fP"
.IP "\fB\-\-untrust=repository\fP"
Overrides trust settings for a repository. May be specified more than once.
.IP
The repository should be specified using the name of a configured remote,
or the UUID or description of a repository.
.IP
.IP "\fB\-\-trust\-glacier\-inventory\fP"
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.
.IP
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!
.IP
.IP "\fB\-\-backend=name\fP"
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.
.IP
.IP "\fB\-\-user\-agent=value\fP"
Overrides the User\-Agent to use when downloading files from the web.
.IP
.IP "\fB\-\-notify\-finish\fP"
Caused a desktop notification to be displayed after each successful
file download and upload.
.IP
(Only supported on some platforms, e.g. Linux with dbus. A no\-op when
not supported.)
.IP
.IP "\fB\-\-notify\-start\fP"
Caused a desktop notification to be displayed when a file upload
or download has started, or when a file is dropped.
.IP
.IP "\fB\-c name=value\fP"
Overrides git configuration settings. May be specified multiple times.
.IP
.SH CONFIGURATION VIA .git/config
Like other git commands, git\-annex is configured via \fB.git/config\fP.
Here are all the supported configuration settings.
.PP
.IP "\fBannex.uuid\fP"
A unique UUID for this repository (automatically set).
.IP
.IP "\fBannex.backends\fP"
Space\-separated list of names of the key\-value backends to use.
The first listed is used to store new files by default.
.IP
.IP "\fBannex.diskreserve\fP"
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"
.IP
The default reserve is 1 megabyte.
.IP
.IP "\fBannex.largefiles\fP"
Allows configuring which files \fBgit annex add\fP and the assistant consider
to be large enough to need to be added to the annex. By default,
all files are added to the annex.
.IP
The value is a preferred content expression. See PREFERRED CONTENT
for details.
.IP
Example:
.IP
 annex.largefiles = largerthan=100kb and not (include=*.c or include=*.h)
.IP
.IP "\fBannex.numcopies\fP"
This is a deprecated setting. You should instead use the
\fBgit annex numcopies\fP command to configure how many copies of files
are kept across all repositories.
.IP
This config setting is only looked at when \fBgit annex numcopies\fP has
never been configured.
.IP
Note that setting numcopies to 0 is very unsafe.
.IP
.IP "\fBannex.genmetadata\fP"
Set this to \fBtrue\fP to make git\-annex automatically generate some metadata
when adding files to the repository.
.IP
In particular, it stores year and month metadata, from the file's
modification date.
.IP
When importfeed is used, it stores additional metadata from the feed.
.IP
.IP "\fBannex.queuesize\fP"
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.
.IP
.IP "\fBannex.bloomcapacity\fP"
The \fBgit annex unused\fP command uses a bloom filter to determine
what data is no longer used. The default bloom filter is sized to handle
up to 500000 keys. If your repository is larger than that,
you can adjust this to avoid \fBgit annex unused\fP not noticing some unused
data files. Increasing this will make \fBgit\-annex unused\fP consume more memory;
run \fBgit annex info\fP for memory usage numbers.
.IP
.IP "\fBannex.bloomaccuracy\fP"
Adjusts the accuracy of the bloom filter used by
\fBgit annex unused\fP. The default accuracy is 1000 \-\-
1 unused file out of 1000 will be missed by \fBgit annex unused\fP. Increasing
the accuracy will make \fBgit annex unused\fP consume more memory;
run \fBgit annex info\fP for memory usage numbers.
.IP
.IP "\fBannex.sshcaching\fP"
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 \fBfalse\fP.
.IP
.IP "\fBannex.alwayscommit\fP"
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 \fB\-c annex.alwayscommit=false\fP. You can later
commit the data by running \fBgit annex merge\fP (or by automatic merges)
or \fBgit annex sync\fP.
.IP
.IP "\fBannex.hardlink\fP"
Set this to \fBtrue\fP to make file contents be hard linked into the
repository when possible, instead of a more expensive copy.
.IP
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.
.IP
When a repository is set up using \fBgit clone \-\-shared\fP, git\-annex init
will automatically set annex.hardlink and mark the repository as
untrusted.
.IP
.IP "\fBannex.delayadd\fP"
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.
.IP
.IP "\fBannex.expireunused\fP"
Controls what the assistant does about unused file contents
that are stored in the repository.
.IP
The default is \fBfalse\fP, 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).
.IP
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.
.IP
.IP "\fBannex.fscknudge\fP"
When set to false, prevents the webapp from reminding you when using
repositories that lack consistency checks.
.IP
.IP "\fBannex.autoupgrade\fP"
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.
.IP
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.
.IP
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.
.IP
.IP "\fBannex.autocommit\fP"
Set to false to prevent the git\-annex assistant from automatically
committing changes to files in the repository.
.IP
.IP "\fBannex.startupscan\fP"
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.
.IP
.IP "\fBannex.listen\fP"
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.
.IP
.IP "\fBannex.debug\fP"
Set to true to enable debug logging by default.
.IP
.IP "\fBannex.version\fP"
Automatically maintained, and used to automate upgrades between versions.
.IP
.IP "\fBannex.direct\fP"
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.
.IP
.IP "\fBannex.crippledfilesystem\fP"
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".
.IP
.IP "\fBremote.<name>.annex\-cost\fP"
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.
.IP
.IP "\fBremote.<name>.annex\-cost\-command\fP"
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.
.IP
.IP "\fBremote.<name>.annex\-start\-command\fP"
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.
.IP
The command may be run repeatedly when multiple git\-annex processes
are running concurrently.
.IP
.IP "\fBremote.<name>.annex\-stop\-command\fP"
A command to run when git\-annex is done using the remote.
.IP
The command will only be run once *all* running git\-annex processes
are finished using the remote.
.IP
.IP "\fBremote.<name>.annex\-shell\fP"
Specify an alternative git\-annex\-shell executable on the remote
instead of looking for "git\-annex\-shell" on the PATH.
.IP
This is useful if the git\-annex\-shell program is outside the PATH
or has a non\-standard name.
.IP
.IP "\fBremote.<name>.annex\-ignore\fP"
If set to \fBtrue\fP, prevents git\-annex
from storing file contents on this remote by default.
(You can still request it be used by the \fB\-\-from\fP and \fB\-\-to\fP options.)
.IP
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.
.IP
This does not prevent git\-annex sync (or the git\-annex assistant) from
syncing the git repository to the remote.
.IP
.IP "\fBremote.<name>.annex\-sync\fP"
If set to \fBfalse\fP, prevents git\-annex sync (and the git\-annex assistant)
from syncing with this remote.
.IP
.IP "\fBremote.<name>.annex\-readonly\fP"
If set to \fBtrue\fP, 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.
.IP
.IP "\fBremote.<name>.annexUrl\fP"
Can be used to specify a different url than the regular \fBremote.<name>.url\fP
for git\-annex to use when talking with the remote. Similar to the \fBpushUrl\fP
used by git\-push.
.IP
.IP "\fBremote.<name>.annex\-uuid\fP"
git\-annex caches UUIDs of remote repositories here.
.IP
.IP "\fBremote.<name>.annex\-trustlevel\fP"
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".
.IP
.IP "\fBremote.<name>.annex\-availability\fP"
Can be used to tell git\-annex whether a remote is LocallyAvailable
or GloballyAvailable. Normally, git\-annex determines this automatically.
.IP
.IP "\fBremote.<name>.annex\-bare\fP"
Can be used to tell git\-annex if a remote is a bare repository
or not. Normally, git\-annex determines this automatically.
.IP
.IP "\fBremote.<name>.annex\-ssh\-options\fP"
Options to use when using ssh to talk to this remote.
.IP
.IP "\fBremote.<name>.annex\-rsync\-options\fP"
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 \fB\-6 \-\-bwlimit 100\fP
.IP
.IP "\fBremote.<name>.annex\-rsync\-upload\-options\fP"
Options to use when using rsync to upload a file to a remote.
.IP
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 \fB\-\-bwlimit 10\fP.
.IP
.IP "\fBremote.<name>.annex\-rsync\-download\-options\fP"
Options to use when using rsync to download a file from a remote.
.IP
These options are passed after other applicable rsync options,
so can be used to override them.
.IP
.IP "\fBremote.<name>.annex\-rsync\-transport\fP"
The remote shell to use to connect to the rsync remote. Possible
values are \fBssh\fP (the default) and \fBrsh\fP, together with their
arguments, for instance \fBssh \-p 2222 \-c blowfish\fP; Note that the
remote hostname should not appear there, see rsync(1) for details.
When the transport used is \fBssh\fP, connections are automatically cached
unless \fBannex.sshcaching\fP is unset.
.IP
.IP "\fBremote.<name>.annex\-bup\-split\-options\fP"
Options to pass to bup split when storing content in this remote.
For example, to limit the bandwidth to 100Kbyte/s, set it to \fB\-\-bwlimit 100k\fP
(There is no corresponding option for bup join.)
.IP
.IP "\fBremote.<name>.annex\-gnupg\-options\fP"
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 \fB\-\-cipher\-algo AES256 \-\-compress\-algo none\fP. (These options take
precedence over the default GnuPG configuration, which is otherwise
used.)
.IP
.IP "\fBannex.ssh\-options\fP, \fBannex.rsync\-options\fP,"
\fBannex.rsync\-upload\-options\fP, \fBannex.rsync\-download\-options\fP,
\fBannex.bup\-split\-options\fP, \fBannex.gnupg\-options\fP
.IP
Default options to use if a remote does not have more specific options
as described above.
.IP
.IP "\fBannex.web\-options\fP"
Options to pass when running wget or curl.
For example, to force ipv4 only, set it to "\-4"
.IP
.IP "\fBannex.quvi\-options\fP"
Options to pass to quvi when using it to find the url to download for a
video.
.IP
.IP "\fBannex.aria\-torrent\-options\fP"
Options to pass to aria2c when using it to download a torrent.
.IP
.IP "\fBannex.http\-headers\fP"
HTTP headers to send when downloading from the web. Multiple lines of
this option can be set, one per header.
.IP
.IP "\fBannex.http\-headers\-command\fP"
If set, the command is run and each line of its output is used as a HTTP
header. This overrides annex.http\-headers.
.IP
.IP "\fBannex.web\-download\-command\fP"
Use to specify a command to run to download a file from the web.
(The default is to use wget or curl.)
.IP
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.
.IP
.IP "\fBannex.secure\-erase\-command\fP"
This can be set to a command that should be run whenever git\-annex
removes the content of a file from the repository.
.IP
In the command line, %file is replaced with the file that should be
erased.
.IP
For example, to use the wipe command, set it to \fBwipe \-f %file\fP.
.IP
.IP "\fBremote.<name>.rsyncurl\fP"
Used by rsync special remotes, this configures
the location of the rsync repository to use. Normally this is automatically
set up by \fBgit annex initremote\fP, but you can change it if needed.
.IP
.IP "\fBremote.<name>.buprepo\fP"
Used by bup special remotes, this configures
the location of the bup repository to use. Normally this is automatically
set up by \fBgit annex initremote\fP, but you can change it if needed.
.IP
.IP "\fBremote.<name>.ddarrepo\fP"
Used by ddar special remotes, this configures
the location of the ddar repository to use. Normally this is automatically
set up by \fBgit annex initremote\fP, but you can change it if needed.
.IP
.IP "\fBremote.<name>.directory\fP"
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 \fBgit annex initremote\fP,
but you can change it if needed.
.IP
.IP "\fBremote.<name>.s3\fP"
Used to identify Amazon S3 special remotes.
Normally this is automatically set up by \fBgit annex initremote\fP.
.IP
.IP "\fBremote.<name>.glacier\fP"
Used to identify Amazon Glacier special remotes.
Normally this is automatically set up by \fBgit annex initremote\fP.
.IP
.IP "\fBremote.<name>.webdav\fP"
Used to identify webdav special remotes.
Normally this is automatically set up by \fBgit annex initremote\fP.
.IP
.IP "\fBremote.<name>.tahoe\fP"
Used to identify tahoe special remotes.
Points to the configuration directory for tahoe.
.IP
.IP "\fBremote.<name>.annex\-xmppaddress\fP"
Used to identify the XMPP address of a Jabber buddy.
Normally this is set up by the git\-annex assistant when pairing over XMPP.
.IP
.IP "\fBremote.<name>.gcrypt\fP"
Used to identify gcrypt special remotes.
Normally this is automatically set up by \fBgit annex initremote\fP.
.IP
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".
.IP
.IP "\fBremote.<name>.hooktype\fP, \fBremote.<name>.externaltype\fP"
Used by hook special remotes and external special remotes to record
the type of the remote.
.IP
.IP "\fBannex.tune.objecthash1\fP, \fBannex.tune.objecthashlower\fP, \fBannex.tune.branchhash1\fP"
These can be passed to \fBgit annex init\fP to tune the repository.
They cannot be safely changed in a running repository.
For details, see <http://git\-annex.branchable.com/tuning/>.
.IP
.SH 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 \fB.gitattributes\fP files. In the file,
the \fBannex.backend\fP 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:
.PP
 * annex.backend=WORM
 *.ogg annex.backend=SHA256E
.PP
The numcopies setting can also be configured on a per\-file\-type basis via
the \fBannex.numcopies\fP attribute in \fB.gitattributes\fP files. This overrides
other numcopies settings.
For example, this makes two copies be needed for wav files and 3 copies
for flac files:
.PP
 *.wav annex.numcopies=2
 *.flac annex.numcopies=3
.PP
Note that setting numcopies to 0 is very unsafe.
.PP
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.
.PP
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.
.PP
.SH FILES
These files are used by git\-annex:
.PP
\fB.git/annex/objects/\fP in your git repository contains the annexed file
contents that are currently available. Annexed files in your git
repository symlink to that content.
.PP
\fB.git/annex/\fP in your git repository contains other run\-time information
used by git\-annex.
.PP
\fB~/.config/git\-annex/autostart\fP is a list of git repositories
to start the git\-annex assistant in.
.PP
\fB.git/hooks/pre\-commit\-annex\fP 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.
.PP
\fB.git/hooks/post\-update\-annex\fP in your git repository will be run
whenever the git\-annex branch is updated. You can make this hook run
\fBgit update\-server\-info\fP when publishing a git\-annex repository by http.
.PP
.SH SEE ALSO
More git\-annex documentation is available on its web site,
<http://git\-annex.branchable.com/>
.PP
If git\-annex is installed from a package, a copy of its documentation
should be included, in, for example, \fB/usr/share/doc/git\-annex/\fP.
