How can I run git commands on Windows with SSH verbose mode?

If your PATH is correctly set:

• you don't need OpenSSH-Win64 (ssh is already included in Git)
• you don't need to specify the full path for SSH

You need:

set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%

Then

set GIT_SSH_COMMAND=ssh -vvv

You can force git to provide verbose ssh output with the "GIT_SSH_COMMAND" environment variable.

For example, to get verbose output from OpenSSH-For-Windows for a git clone command, just open a command prompt and enter

set GIT_SSH_COMMAND="C:\Program Files\OpenSSH-Win64\ssh.exe" -vvv
git clone <repo_ssh_url>
