Options in svnsync are global, just as they are in svn and svnadmin:
--config-dir
DIR
Instructs Subversion to read configuration information from the specified directory instead of the default location (.subversion in the user’s home directory).
--no-auth-cache
Prevents caching of authentication information (e.g., username and password) in the Subversion runtime configuration directories.
--non-interactive
In the case of an authentication failure or insufficient credentials, prevents prompting for credentials (e.g., username or password). This is useful if you’re running Subversion inside an automated script and it’s more appropriate to have Subversion fail than to prompt for more information.
--quiet
(-q
)Requests that the client print only essential information while performing an operation.
--source-password
PASSWD
Specifies the password for the Subversion server from which you are syncing. If not provided, or if incorrect, Subversion will prompt you for this information as needed.
--source-username
NAME
Specifies the username for the Subversion server from which you are syncing. If not provided, or if incorrect, Subversion will prompt you for this information as needed.
--sync-password
PASSWD
Specifies the password for the Subversion server to which you are syncing. If not provided, or if incorrect, Subversion will prompt you for this information as needed.
--sync-username
NAME
Specifies the username for the Subversion server to which you are syncing. If not provided, or if incorrect, Subversion will prompt you for this information as needed.
