如何將 scp 和 ssh 安裝到 Powershell？

Question

我使用以下命令安裝了 Posh-SSH：Install-Module -Name Posh-SSH

嘗試執行 scp 或 ssh 時，我得到如下內容。 為什么？

scp : The term 'scp' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ scp
+ ~~~
    + CategoryInfo          : ObjectNotFound: (scp:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

更新在@tommymaynard 的幫助下，我可以看到所有可用的命令：

PS C:\WINDOWS\system32> $x = Find-Module -Name Posh-SSH
PS C:\WINDOWS\system32> $x.AdditionalMetadata.Functions -split ' '
Get-PoshSSHModVersion

從那里，您將使用哪個命令來替換下面的“scp”和“ssh”（參考： https : //code.visualstudio.com/docs/remote/troubleshooting#_configuring-key-based-authentication ）？

$REMOTEHOST="your-user-name-on-host@host-fqdn-or-ip-goes-here"

scp "$env:USERPROFILE\.ssh\id_rsa.pub" "${REMOTEHOST}:~/tmp.pub"
ssh "$REMOTEHOST" "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat ~/tmp.pub >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys && rm -f ~/tmp.pub"

您安裝的模塊不包含名為“scp”的函數/cmdlet。 我沒有安裝模塊，但確實運行了以下命令來確定模塊中函數和 cmdlet 的名稱。

$x = Find-Module -Name Posh-SSH
$x.AdditionalMetadata.Functions -split ' '
$x.AdditionalMetadata.Cmdlets -split ' '

編輯：您是否閱讀了 *scp* 命令的幫助？ 我做到了。 其中之一一定會做你需要的。 我繼續在我的計算機上安裝了該模塊並運行以下命令以快速獲取此模塊中 *scp* 命令的概要。

Install-Module -Name Posh-SSH
Get-Command -Module Posh-SSH -Name *scp* |
ForEach-Object {"$($_.Name): $((Get-Help -Name $_).Synopsis)"}
