Appreciating *nix commands in Windows PowerShell

#region Fix important *nix commands.

# PowerShell comes with some predefined aliases built-in that are designed to
# ease the transition from *nix to PowerShell. While this is well-intentioned,
# it hides the true power that is available in these *nix commands, and it
# makes it much more difficult to compare and contrast between native commands
# in PowerShell and their *nix counterparts. This block of code removes the
# predefined aliases that would otherwise hide these important *nix commands.

foreach ($nixCommand in @('cat','cp','curl','diff','echo','kill','ls','man','mount','mv','ps','pwd','rm','sleep','tee','type','wget')) {
    if (Test-Path -LiteralPath alias:${nixCommand}) {
        Remove-Item -LiteralPath alias:${nixCommand} -Force
    }
}

New-Alias -Name type -Value cat

function ls {
    param()
    if ($args -notcontains '--color') {
        $args += '--color'
    }
    & ls.exe @args
}
