How can I tell if a specified folder is in my PATH using PowerShell?

How can I tell if a specified folder is in my PATH using PowerShell?

A function like this would be great:

function FolderIsInPATH($Path_to_directory) {
    # If the directory is in PATH, return true, otherwise false
}
Solution

  • Going off this question, you don't need a function for this but can retrieve this with $Env:Path:

    $Env:Path -split ";" -contains $directory

    The -contains operator is case-insensitive which is a bonus. It could be useful placing this in a function to ensure trailing slashes are trimmed, but that's uncommon:

    function inPath($directory) {
    return ($Env:Path -split ';').TrimEnd('\') -contains $directory.TrimEnd('\')
}
