# NAME
-git-annex reinject - sets content of annexed file
+git-annex reinject - inject content of file back into annex
# SYNOPSIS
-git annex reinject `src dest`
+git annex reinject `[src dest]`
+
+git annex reinject --known `[src]`
# DESCRIPTION
-Moves the src file into the annex as the content of the dest file,
-which should be an already annexed file whose content is not present.
+Moves the content of the src file or files into the annex.
+Only known file contents will be reinjected. Any unknown src files will
+be left unchanged.
This can be useful if you have obtained the content of a file from
-elsewhere and want to put it in the local annex.
-
-Verifies that the src file's content matches with the content that the dest
-file is expected to have, and refuses to reinject it otherwise.
+elsewhere and want to put it in the local annex. For example, if a file's
+content has been lost and you have a backup, you can restore the backup and
+reinject it into your local repository.
-Example:
+There are two ways to use this command. Specifying a src file and the name
+of a dest file (located inside the repository's working tree)
+injects the src file as the content of the dest file.
git annex reinject /tmp/foo.iso foo.iso
+Or the `--known` option can be used to reinject all known src files, without
+needing to specify the dest file.
+
+ git annex reinject --known /tmp/*.iso
+
+# OPTIONS
+
+* `--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 file having been in the annex before, the content is
+ reinjected.
+
+ 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.

None of the `git annex import` modes work properly in this case. By default, importing adds another, unnecessary copy of the imported file (which I have to `rm` after importing). The `--clean-duplicates` mode seems close, but it insists on verifying the content in other repositories rather than just reinjecting it locally. (Let's assume that the main reason I'm trying to reinject is that I cannot access other repos.)
So I'm hoping for something like `git annex import --reinject <src>...`. Or are there other existing ways to achieve the same? I couldn't find any.
