git-annex-shell(1)					      General Commands Manual						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 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. commit directory This commits any staged changes to the git-annex branch. It also runs the annex-content hook. 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. 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-con- tent 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. GIT_ANNEX_SHELL_LIMITED If set, disallows running git-shell to handle unknown commands. SEE ALSO
