PowerShell script to copy SSH public key to a Linux system. This is for my article on OpenSSH - https://www.jhanley.com/ubuntu-20-04-desktop-installing-and-configuring-ssh/

ssh-copy-id.bat

powershell ./ssh-copy-id.ps1 %1 %2

ssh-copy-id.ps1

if ($args.count -lt 1)
{
	Write-Host "Error: Missing filename"
	Write-Host "Usage: ssh-copy-id.ps1 <public-key-filename> <username@host>"
	Exit
}

if ($args.count -lt 2)
{
	Write-Host "Error: Missing username@host string"
	Write-Host "Usage: ssh-copy-id.ps1 <public-key-filename> <username@host>"
	Exit
}

$key = $args[0]
$sshhost = $args[1]

if (-not(Test-Path $key -PathType Leaf)) {
	Write-Host "Error: file does not exist"
	Write-Host "File: $key"
	Exit
}

Write-Host "Installing SSH publilc key: $key to host $sshhost"

type $key | ssh $sshhost "if [ ! -d .ssh ]; then mkdir .ssh; fi && cat >> ~/.ssh/authorized_keys"
