如何从 PowerShell 脚本打开另一个 PowerShell 控制台

How to open another PowerShell console from a PowerShell script

在 OSX 中,我打开 bash 终端并进入 PowerShell 控制台。 在我的 PowerShell 脚本中,我想打开另一个 PowerShell 控制台并在那里执行 PowerShell 脚本。

在 Windows 下,我会

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

我怎么能在 OSX 中做同样的事情?

我对 mac 上的 powershell 一无所知,如果它存在的话,我只能在 Mac OS 上打开一个类似终端的 gui 应用程序 X你可以使用打开命令:

open -a /Applications/Utilities/Terminal.app "" 将是一个新的空白 window
open -a /Applications/Utilities/Terminal.app somescrip.sh 将是 运行 一个脚本

或者你可以制作一个 apple 脚本 运行 那

将以下内容保存在文件中 (~/OpenNewTerminal.scp):

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

然后你可以 运行 用 osascript

osascript ~/OpenNewTerminal.scp

当然,更 bash 惯用的方式是 运行 在子 shell 或后台

subshell:

output=$(ls)
echo $output

背景:

./command &

具有重定向输出的背景,因此它不会渗透到您当前的 shell:

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

在 macOSwindow 上的新终端 window 中启动 PowerShell 实例:


无法向其传递参数:

PS> open -a Terminal $PSHOME/powershell

如果你想运行一个给定的命令:

不幸的是,如果您想在新的 PowerShell 实例中将命令传递给 运行,还需要做更多的工作:
本质上,您需要将您的命令放在一个临时的、自删除的、可执行的 shell 脚本中,该脚本通过 shebang 行调用:

注意:确保 运行 至少 PowerShell Core v6.0.0-beta.6 才能正常工作。

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

}

定义此函数后,您可以使用给定命令调用 PowerShell - 指定为脚本块 - 如下所示:

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