我试图找到一种在ScriptBlock Invoke-Command范围内达到峰值的简单方法。我已经阅读了Hey Scripting Guy博客，但他们只调用了脚本文件，我对如何做到这一点感到有些困惑。
有人可以告诉我如何让调试器停在说$Var = 5行吗？我曾尝试Set-PSBreakpoint，但总是失败。这样可以方便地检查值以及所有代码是否正确。
代码示例：
$session = New-PSSession -ComputerName localhost
Invoke-Command -Session $session -ScriptBlock $LoadFunctions
# Do other stuff
Invoke-Command -Session $session -ScriptBlock {
$Time = Get-Date
$Var = '5' # Stop debugger here
Set-PSBreakpoint -Variable $Var
}
Remove-PSSession $Session
感谢您的帮助。

这对我有用。顺便说一下，我在PowerShell 4.0中。
首先，我将先前的set-psbreakpoint放在scriptblock中：
Invoke-Command -ComputerName . -ScriptBlock {
Set-PSBreakpoint -Variable metoo;
$test="foo";
$one="1";
$metoo="metoo";
} -Credential (Get-Credential)
当我跑步时，我收到以下消息：
WARNING: Session Session8 with instance ID 4a02c5f4-b333-4e58-85b7-78ccd4f31318 on computer localhost has been
disconnected because the script running on the session has stopped at a breakpoint. Use the Enter-PSSession cmdlet on
this session to connect back to the session and begin interactive debugging.
WARNING: Session Session8 with instance ID 4a02c5f4-b333-4e58-85b7-78ccd4f31318 has been created for reconnection.
所以为了看到会话仍在那里，我做了一个Get-PSSession：
> Get-PSSession
Id Name ComputerName State ConfigurationName Availability
-- ---- ------------ ----- ----------------- ------------
9 Session8 localhost Disconnected Microsoft.PowerShell None
很棒，会话就在那里，只需要重新连接并输入：
> Get-PSSession | Connect-PSSession
Id Name ComputerName State ConfigurationName Availability
-- ---- ------------ ----- ----------------- ------------
9 Session8 localhost Opened Microsoft.PowerShell RemoteDebug
进入会话：
> Get-PSSession | Enter-PSSession

很好，所以现在我在远程调试会话中！只需按照提示操作，例如输入“h”获取帮助或输入“k”获取-psscallstack等
[localhost]: [DBG]: PS C:\Users\Foo\Documents>> h
s, stepInto Single step (step into functions, scripts, etc.)
v, stepOver Step to next statement (step over functions, scripts, etc.)
o, stepOut Step out of the current function, script, etc.
c, continue Continue operation
q, quit Stop operation and exit the debugger
k, Get-PSCallStack Display call stack
l, list List source code for the current script.
Use "list" to start from the current line, "list <m>"
to start from line <m>, and "list <m> <n>" to list <n>
lines starting from line <m>
<enter> Repeat last command if it was stepInto, stepOver or list
?, h displays this help message.
