    Noob to PS, but I know bash and batch.

    I'm trying to do a simple script that tests the existence of a file and then creates another depending on the outcome, but prompts me for a parameter value after running it.

    function test-existence {
    if(test-path -path "C:\testran.flag") {echo > C:\users\admin\desktop\true.flag}
    if(!(test-path -path "C:\testfailed.flag")) {echo > C:\users\admin\desktop\false.flag}
    I've tried running it as a function and just as a two line script, but it still produces the same result.

    [quote]Supply values for the following parameters:
    InputObject[0]]This is part of a fully automated setup so I need this to run without any user interaction.

    echo is an alias for write-output, and if you don't tell it what it has to write, it will ask you.
    try Get-Help echo -full
    Maybe you want to use New-Item instead:
    if(test-path -path "C:\testran.flag") {New-Item -Type file -Path C:\users\admin\desktop\true.flag}

    Solved it using Add-Content

    function test-existence
    if(test-path -path "C:\testran.flag") {Add-Content C:\users\admin\desktop\true.flag ""}
    if(!(test-path -path "C:\testfailed.flag")) {Add-Content C:\users\admin\desktop\false.flag ""}
