ssh.variant:: By default, Git determines the command line arguments to use based on the basename of the configured SSH command (configured using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or the config setting `core.sshCommand`). If the basename is unrecognized, Git will attempt to detect support of OpenSSH options by first invoking the configured SSH command with the `-G` (print configuration) option and will subsequently use OpenSSH options (if that is successful) or no options besides the host and remote command (if it fails). + The config variable `ssh.variant` can be set to override this detection. Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`, `tortoiseplink`, `simple` (no options except the host and remote command). The default auto-detection can be explicitly requested using the value `auto`. Any other value is treated as `ssh`. This setting can also be overridden via the environment variable `GIT_SSH_VARIANT`. + The current command-line parameters used for each variant are as follows: + -- * `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command * `simple` - [username@]host command * `plink` or `putty` - [-P port] [-4] [-6] [username@]host command * `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command -- + Except for the `simple` variant, command-line parameters are likely to change as git gains new features.
