ssh-copy-id for Windows

"""ssh-copy-id for Windows.

Example usage: python ssh-copy-id.py ceilfors@my-remote-machine

This script is dependent on msysgit by default as it requires scp and ssh.
For convenience you can also try that comes http://bliker.github.io/cmder/.

Any chance to add a custom port?
UPDATE: just did, see my fork ;)

@ferielboa: just copy this text and save it as ssh-copy-id.py. Then, from the folder where you saved it call python ssh-copy-id.py ceilfors@my-remote-machine. You can also add a custom port for the ssh/scp connection in my fork with the -p flag. It will ask you to login twice, once for the scp and once for the ssh connection.

Hi, can you please tell me with which version of python this script is compatible? I am trying to run it on win 10 python 3.8 but I get the following error

python ssh-copy-id.py salam@fedora
