非交互模式的 Powershell 测试 [英] Powershell test for noninteractive mode
问题描述
我有一个可以手动运行或由计划任务运行的脚本.我需要以编程方式确定我是在 -noninteractive 模式(通过计划任务运行时设置)还是正常模式下运行.我已经用谷歌搜索了，我能找到的最好的方法是添加一个命令行参数，但我没有任何可行的方法来处理计划任务，也不能合理地期望用户在运行时添加参数手动.非交互模式是否设置了某种变量或我可以在脚本中检查的内容?
I have a script that may be run manually or may be run by a scheduled task. I need to programmatically determine if I'm running in -noninteractive mode (which is set when run via scheduled task) or normal mode. I've googled around and the best I can find is to add a command line parameter, but I don't have any feasible way of doing that with the scheduled tasks nor can I reasonably expect the users to add the parameter when they run it manually. Does noninteractive mode set some kind of variable or something I could check for in my script?
我实际上无意中回答了我自己的问题，但我将它留在这里以供后代使用.
I actually inadvertently answered my own question but I'm leaving it here for posterity.
我在脚本中插入了一个读取主机来询问用户一些事情，当它在非交互模式下运行时，繁荣，终止错误.将其卡在 try/catch 块中，并根据我所处的模式执行操作.
I stuck a read-host in the script to ask the user for something and when it ran in noninteractive mode, boom, terminating error. Stuck it in a try/catch block and do stuff based on what mode I'm in.
不是最漂亮的代码结构，但它有效.如果其他人有更好的方法，请添加它！
Not the prettiest code structure, but it works. If anyone else has a better way please add it!
推荐答案
您可以使用 Get-WmiObject 用于 WMI 对象:
You can check how powershell was called using Get-WmiObject for WMI objects:
(gwmi win32_process | ? { $_.processname -eq "powershell.exe" }) | select commandline
#commandline
#-----------
#"C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe" -noprofile -NonInteractive
更新:2020-10-08
UPDATE: 2020-10-08
从 PowerShell 3.0 开始，此 cmdlet 已被 Get-CimInstance
Starting in PowerShell 3.0, this cmdlet has been superseded by
Get-CimInstance
(Get-CimInstance win32_process -Filter "ProcessID=$PID" | ? { $_.processname -eq "pwsh.exe" }) | select commandline
#commandline
#-----------
#"C:\Program Files\PowerShell\6\pwsh.exe"
