如何從PowerShell腳本打開另一個PowerShell控制檯

Question

在OSX中，我打開一個bash終端並輸入一個PowerShell控制檯。 在我的PowerShell腳本中，我想打開另一個PowerShell控制檯並在那裏執行PowerShell腳本。

在Windows下，我會做

Invoke-Expression ('cmd /c start powershell -Command test.ps1') 

我怎麼能這樣做在OSX的samething？

Answer 1

要在MacOS在一個新的終端窗口啓動PowerShell的實例：

---

無能夠傳遞參數：

PS> open -a Terminal $PSHOME/powershell 

---

如果你想運行一個給定的命令：

不幸的是，如果你想通過一個命令在新的PowerShell實例運行需要相當多的工作：
從本質上講，你需要將您的命令在一個臨時的，自我刪除，可執行的shell腳本，通過認領行調用：

^{注：一定要運行至少PowerShell核心V6.0.0-beta.6此上班。}

Function Start-InNewWindowMacOS { 
    param(
    [Parameter(Mandatory)] [ScriptBlock] $ScriptBlock, 
    [Switch] $NoProfile, 
    [Switch] $NoExit 
) 

    # Construct the shebang line 
    $shebangLine = '#!/usr/bin/env powershell' 
    # Add options, if specified: 
    # As an aside: Fundamentally, this wouldn't work on Linux, where 
    # the shebang line only supports *1* argument, which is `powershell` in this case. 
    if ($NoExit) { $shebangLine += ' -NoExit' } 
    if ($NoProfile) { $shebangLine += ' -NoProfile' } 

    # Create a temporary script file 
    $tmpScript = New-TemporaryFile 

    # Add the shebang line, the self-deletion code, and the script-block code. 
    # Note: 
    #  * The self-deletion code assumes that the script was read *as a whole* 
    #  on execution, which assumes that it is reasonably small. 
    #  Ideally, the self-deletion code would use 
    #  'Remove-Item -LiteralPath $PSCommandPath`, but, 
    #  as of PowerShell Core v6.0.0-beta.6, this doesn't work due to a bug 
    #  - see https://github.com/PowerShell/PowerShell/issues/4217 
    #  * UTF8 encoding is desired, but -Encoding utf8, regrettably, creates 
    #  a file with BOM. For now, use ASCII. 
    #  Once v6 is released, BOM-less UTF8 will be the *default*, in which 
    #  case you'll be able to use `> $tmpScript` instead. 
    $shebangLine, "Remove-Item -LiteralPath '$tmpScript'", $ScriptBlock.ToString() | 
    Set-Content -Encoding Ascii -LiteralPath $tmpScript 

    # Make the script file executable. 
    chmod +x $tmpScript 

    # Invoke it in a new terminal window via `open -a Terminal` 
    # Note that `open` is a macOS-specific utility. 
    open -a Terminal -- $tmpScript 

} 

使用此功能定義，你可以用一個給定的命令調用的PowerShell - 指定爲一個腳本塊 - 如下：

# Sample invocation 
Start-InNewWindowMacOS -NoExit { Get-Date }

我不知道在Mac PowerShell的東西，如果存在的話，但打開像Mac OS X上的終端就可以使用命令打開一個GUI應用程序：

open -a /Applications/Utilities/Terminal.app ""將是一個新的空白窗口
open -a /Applications/Utilities/Terminal.app somescrip.sh將運行一個腳本

，或者你可以讓一個蘋果腳本並運行

保存以下的文件（〜/ OpenNewTerminal.scp）：

tell application "Terminal" 
    do script " " 
    activate 
end tell 

那麼你就可以osascript運行

osascript ~/OpenNewTerminal.scp

當然

更bash的慣用方式是在子shell或後臺

子shell中運行：

output=$(ls) 
echo $output 

背景：

./command & 

背景重定向輸出，因此不會滲入你當前的shell：

./command 2>&1 > /dev/null
