如何将scp和ssh安装到Powershell?

Question

我安装了Posh-SSH：安装模块-名称Posh-SSH

尝试执行 scp 或 ssh 时，我得到如下所示的内容。为什么？

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的帮助下，我可以看到所有可用的命令：

PS C:WINDOWSsystem32> $x = Find-Module -Name Posh-SSH
PS C:WINDOWSsystem32> $x.AdditionalMetadata.Functions -split ' '
Get-PoshSSHModVersion

从那里，您将使用哪个命令来替换下面的"scp"和"ssh"(参考：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.sshid_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"

Answer 1

安装的模块不包含名为"scp"的函数/cmdlet。我没有安装该模块，但运行了以下命令来确定模块中函数和 cmdlet 的名称。

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

编辑：您是否阅读了* scp*命令的帮助？我做了。其中之一一定会做你需要的。我继续在我的计算机上安装了该模块并运行以下命令以快速获取该模块中 *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)"}
Get-SCPFile: Download a File from a SSH Server using SCP
Get-SCPFolder: Download a folder from a SSH Server using SCP.
