Powershell uses different syntax than Linux for issuing directory commands. However, Powershell allows users to issue Linux commands in their own form, but behind the scenes powershell is still issuing the commands in a known Windows syntax. Powershell is object-oriented and uses a "Verb-Noun" naming convention. The perameters "ls -a" would translate to "Get-ChildItem -Hidden" in Powershell or "Get-ChildItem -Force".

You might also try installing Windows Subsystem for Linux which will allow you to execute native linux commands from WSL terminal or within Powershell by affixing WSL to the start of your linux command.
