Execute a powershell script via ssh

run.bat

# Notes:
# 1) The input format must be specified to prevent ssh from hanging
# 2) The full path to the script is required
# 3) An SSH server must be running on the Windows box, naturally.  WinSSHD
#    is free for personal, non-commercial use and worked for this example.
#    See http://www.bitvise.com/winsshd
#
# You have to set the execution policy for scripts so that powershell has
# permissions to run the script.  To do so, search for 'Powershell' under
# the Start menu.  Then right-click and 'Run as administrator' so that you
# have permissions to set permissions.  Then:
#
#   PS> Set-ExecutionPolicy RemoteSigned
#
# As a result you can run scripts you write but not unsigned ones from 
# remote sources.  See http://technet.microsoft.com/en-us/library/ee176949.aspx
#
# To execute via ssh:
#
#   $ ssh user@host '"C:\path\to\run.bat"'
#
# Note the inner quotes are superfluous here but required if the path has
# a space in it.
powershell -InputFormat None -F "C:\script.ps1"

script.ps1

# As per the bat file, put this at "C:\script.ps1"
echo "hello world"
