--known
With this option, each specified src file is hashed using the default key-value backend (or the
one specified with --backend), and if git-annex has a record of the resulting key having been in
the annex before, the content is reinjected.
Note that, when using a key-value backend that includes the filename extension in the key, this
will only work if the src files have the same extensions as the files with the same content that
was originally added to git-annex.
Note that this will reinject old versions of files that have been modified or deleted from the
current git branch. Use git-annex-unused(1) to detect when such old and potentially unused files
have been reinjected.
--backend
Specify the key-value backend to use when checking if a file is known with the --known option.
--guesskeys
With this option, each specified source file is checked to see if it has the name of a git-annex
key, and if so it is imported as the content of that key.
This can be used to pluck git-annex objects out of lost+found, as long as the original filename
has not been lost, and is particularly useful when using key-value backends that don't hash to the
content of a file.
When the key-value backend does support hashing, the content of the file is verified before
importing it.
--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-error-messages
Messages that would normally be output to standard error are included in the JSON instead.
Also the git-annex-common-options(1) can be used.
