Solving CMD authorization for git commands

If in your TortoiseGit GUI everything works well, but when running git commands directly from CMD, you get:

git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights

Then one of the possible solutions, you might try is to set “GIT_SSH” for terminal (cmd or powershell) session only at first:

// this is package.json example, just replace "reponame" & "branchname"
{
  "scripts": {
    "PULL-MASTER": "powershell -Command \"$Env:GIT_SSH='C:\\Program Files\\TortoiseGit\\bin\\TortoiseGitPlink.exe'; cd c; git.exe pull --progress -v --no-rebase reponame branchname\""
  }
}

Warning: do not use any of the following approaches for this case:

[System.Environment]::SetEnvironmentVariable("GIT_SSH", "", "User") // or Machine
 //// or ///
git config --global core.sshCommand "tortoiseplink -agent" 
git config --global --unset core.sshCommand

because the first one amends environment variable and second one saves into `%userprofile%\.gitconfig` file and remove that entry.
