[英]Running Powershell command from .bat script doesn't work, however it works when I type it directly in Command Line
[英]Command works directly in Powershell but doesn't work when executed through a linux system using powershell
在 windows 機器中,如果我打開powershell
並編寫此命令,它工作正常。
powershell -command "&{$p='It works'; echo $p}"
這輸出It works
。
但是,如果我使用 linux 機器將ssh放入同一台 windows 機器並嘗試執行此命令,這會給我一個錯誤。
命令:
/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe -command "&{$p='It works'; echo $p}"
當我執行此操作時,會出現以下錯誤:
=It works : The term '=It works' 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:3
+ &{='It works'; echo }
+ ~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (=It works:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
cmdlet Write-Output at command pipeline position 1

InputObject[0]:
我搜索了很多,但找不到背后的原因。 如果有人可以幫助我解決這個問題,我將不勝感激。
您需要轉義$
。 像這樣:
xxx@xxxxx:~$ pwsh -c "&{\$p='It works'; echo \$p}"
It works
添加來自@mklement0的示例,根本不需要執行&
一個 scriptblock { }
(對於這種特定情況),也不需要字符 escaping :
xxx@xxxxx:~$ pwsh -c '$p="It works"; echo $p'
It works
