git-annex-shell(1)

NAME
git-annex-shell - Restricted login shell for git-annex only SSH access

SYNOPSIS
git-annex-shell [-c] command [params ...]

DESCRIPTION
git-annex-shell is a restricted shell, similar to git-shell, which can be used as a login shell for SSH accounts.

Since its syntax is identical to git-shell's, it can be used as a drop-in replacement anywhere git-shell is used. For example it can be used as a user's restricted login shell.

COMMANDS
Any command not listed below is passed through to git-shell.

Note that the directory parameter should be an absolute path, otherwise it is assumed to be relative to the user's home directory. Also the first "/~/" or "/~user/" is expanded to the specified home directory.

configlist directory
    This outputs a subset of the git configuration, in the same form as git config --list. This is used to get the annex.uuid of the remote repository.

    When run in a repository that does not yet have an annex.uuid, one will be created, as long as a git-annex branch has already been pushed to the repository.

inannex directory [key ...]
    This checks if all specified keys are present in the annex, and exits zero if so.

dropkey directory [key ...]
    This drops the annexed data for the specified keys.

recvkey directory key
    This runs rsync in server mode to receive the content of a key, and stores the content in the annex.

sendkey directory key
    This runs rsync in server mode to transfer out the content of a key.

transferinfo directory key
    This is typically run at the same time as sendkey is sending a key to the remote. Using it is optional, but is used to update progress information for the transfer of the key.

    It reads lines from standard input, each giving the number of bytes that have been received so far.

commit directory
    This commits any staged changes to the git-annex branch. It also runs the annex-content hook.

notifychanges
    This is used by git-annex remotedaemon to be notified when refs in the remote repository are changed.

gcryptsetup gcryptid
    Sets up a repository as a gcrypt repository.

OPTIONS
Most options are the same as in git-annex. The ones specific to git-annex-shell are:

--uuid=UUID
    git-annex uses this to specify the UUID of the repository it was expecting git-annex-shell to access, as a sanity check.

-- fields=val fields=val.. --
    Additional fields may be specified this way, to retain compatability with past versions of git-annex-shell (that ignore these, but would choke on new dashed options).

    Currently used fields include remoteuuid=, associatedfile=, and direct=

HOOK
After content is received or dropped from the repository by git-annex-shell, it runs a hook, .git/hooks/annex-content (or hooks/annex-content on a bare repository). The hook is not currently passed any information about what changed.

ENVIRONMENT

GIT_ANNEX_SHELL_READONLY

    If set, disallows any command that could modify the repository.

    Note that this does not prevent passing commands on to git-shell. For that, you also need ...

GIT_ANNEX_SHELL_LIMITED
    If set, disallows running git-shell to handle unknown commands.

GIT_ANNEX_SHELL_DIRECTORY
    If set, git-annex-shell will refuse to run commands that do not operate on the specified directory.
