   1 ssh.variant::
   2         By default, Git determines the command line arguments to use
   3         based on the basename of the configured SSH command (configured
   4         using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
   5         the config setting `core.sshCommand`). If the basename is
   6         unrecognized, Git will attempt to detect support of OpenSSH
   7         options by first invoking the configured SSH command with the
   8         `-G` (print configuration) option and will subsequently use
   9         OpenSSH options (if that is successful) or no options besides
  10         the host and remote command (if it fails).

  12 The config variable `ssh.variant` can be set to override this detection.
  13 Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
  14 `tortoiseplink`, `simple` (no options except the host and remote command).
  15 The default auto-detection can be explicitly requested using the value
  16 `auto`.  Any other value is treated as `ssh`.  This setting can also be
  17 overridden via the environment variable `GIT_SSH_VARIANT`.

  19 The current command-line parameters used for each variant are as
  20 follows:

  22 --
  23
  24 * `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
  25
  26 * `simple` - [username@]host command
  27
  28 * `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
  29
  30 * `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command

  34 Except for the `simple` variant, command-line parameters are likely to
  35 change as git gains new features.
