git-annex-config - Man Page

git annex config --set name value

git annex config --get name

git annex config --unset name

git annex config --show-origin name

Set or get configuration settings stored in the git-annex branch.

Unlike git config settings, these settings can be seen in all clones of the repository, once they have gotten their git-annex branches in sync.

These settings can be overridden on a per-repository basis using git config.

git-annex does not check the git-annex branch for all the git config settings that affect it (which are listed on the git-annex man page CONFIGURATION section). Only a few make sense to be able to set such that all clones of a repository see the setting, and so git-annex only looks for these.

annex.numcopies

Tells git-annex how many copies it should preserve of files, over all repositories. The default is 1.

When git-annex is asked to drop a file, it first verifies that the number of copies can be satisfied among all the other repositories that have a copy of the file.

In unusual situations, involving special remotes that do not support locking, and concurrent drops of the same content from multiple repositories, git-annex may violate the numcopies setting. It still guarantees at least 1 copy is preserved. This can be configured by setting annex.mincopies.

This is the same setting that the git-annex-numcopies(1) command configures. It can be overridden on a per-file basis by the annex.numcopies setting in .gitattributes files.

annex.mincopies

Tells git-annex how many copies it is required to preserve of files,  over all repositories. The default is 1.

This supplements the annex.numcopies setting.  In unusual situations, involving special remotes that do not support locking, and concurrent drops of the same content from multiple repositories, git-annex may violate the numcopies setting. In these unusual situations, git-annex ensures that the number of copies never goes below mincopies.

It is a good idea to not only rely on only setting mincopies. Set numcopies as well, to a larger number, and keep mincopies at the bare minimum you're comfortable with. Setting mincopies to a large number, rather than setting numcopies will in some cases prevent droping content in entirely safe situations.

This is the same setting that the git-annex-mincopies(1) command configures. It can be overridden on a per-file basis by the annex.mincopies setting in .gitattributes files.

annex.largefiles

Used to configure which files are large enough to be added to the annex. It is an expression that matches the large files, eg "include=*.mp3 or largerthan(500kb)". See git-annex-matching-expression(1) for details on the syntax.

This configures the behavior of both git-annex and git when adding files to the repository. By default, git-annex add adds all files to the annex (except dotfiles), and git add adds files to git (unless they were added to the annex previously). When annex.largefiles is configured, both git annex add and git add will add matching large files to the annex, and the other files to git.

Other git-annex commands also honor annex.largefiles, including git annex import, git annex addurl, git annex importfeed, git-annex assist, and the git-annex assistant.

This sets a default, which can be overridden by annex.largefiles attributes in .gitattributes files, or by git config.

annex.dotfiles

Normally, dotfiles are assumed to be files like .gitignore, whose content should always be part of the git repository, so  they will not be added to the annex. Setting annex.dotfiles to true makes dotfiles be added to the annex the same as any other file.

This sets a default, which can be overridden by annex.dotfiles in git config.

annex.addunlocked

Commands like git-annex add default to adding files to the repository in locked form. This can make them add the files in unlocked form, the same as if git-annex-unlock(1) were run on the files.

This can be set to "true" to add everything unlocked, or it can be a more complicated expression that matches files by name, size, or content. See git-annex-matching-expression(1) for details.

This sets a default, which can be overridden by annex.addunlocked in git config.

annex.autocommit

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

This sets a default, which can be overridden by annex.autocommit in git config.

annex.resolvemerge

Set to false to prevent merge conflicts in the checked out branch being automatically resolved by the git-annex assitant, git-annex sync, git-annex pull, git-annex merge,  and the git-annex post-receive hook.

This sets a default, which can be overridden by annex.resolvemerge in git config.

annex.synccontent

Set to true to make git-annex sync default to transferring annexed content.

Set to false to prevent git-annex pull and git-annex push from transferring annexed content.

This sets a default, which can be overridden by annex.synccontent in git config.

annex.synconlyannex

Set to true to make git-annex sync, git-annex pull and git-annex push default to only operate on the git-annex branch and annexed content.

This sets a default, which can be overridden by annex.synconlyannex in git config.

annex.securehashesonly

Set to true to indicate that the repository should only use cryptographically secure hashes (SHA2, SHA3) and not insecure hashes (MD5, SHA1) for content.

When this is set, the contents of files using cryptographically insecure hashes will not be allowed to be added to the repository.

Also, git-annex fsck will complain about any files present in the repository that use insecure hashes.

Note that this is only read from the git-annex branch by git annex init, and is copied to the corresponding git config setting.  So, changes to the value in the git-annex branch won't affect a repository once it has been initialized.

--set name value

Set a value.

--get name

Get a value.

--unset

Unset a value.

--show-origin name

Explain where the value is configured, whether in the git-annex branch, or in a git config file, or .gitattributes file. When a value is configured in multiple places, displays the place and the value that will be used.

Note that the parameter can be the name of one of the settings listed above, but also any other configuration setting supported by git-annex. For example, "annex.backend" cannot be set in the git-annex branch, but it can be set in .gitattributes or git config and this option can explain which setting will be used for it.

--for-file file

Can be used in combination with --show-origin to specify what filename to check for in .gitattributes.

Also the git-annex-common-options(1) can be used.

Suppose you want to prevent git annex sync from committing changes to files, so a manual git commit workflow is used in all clones of the repository. Then run:

git annex config --set annex.autocommit false

If you want to override that in a partiticular clone, just use git config in the clone:

git config annex.autocommit true

And to get back to the default behavior:

git annex config --unset annex.autocommit
