How to pass a variable in the select-string of powershell

问题

There is one requirement where i need to pass a variable that is set in the powershell to the another variable

Please find the below example

    PS D:\temp\arun> $match1=get-date -format ddMMM
    PS D:\temp\arun> $match1
    19Jun

test.txt file has the below content

    19Jun1
    19Jun2
    19Jun3

    PS D:\temp\arun> $match2=select-string -simple 19Jun test.txt
    PS D:\temp\arun> $match2
    19Jun1
    19Jun2
    19Jun3

But when i am trying to pass the variable i am not getting the result.

    PS D:\temp\arun> $match2=select-string -simple $match1 test.txt
    PS D:\temp\arun> $match2

Could any one please help me in this?

Works fine here. Try specifying the paramters to make sure the right value is assigned to the right parameter.

$match2 = Select-String -SimpleMatch -Pattern $match1 -Path .\test.txt
