is Powershell like Perl?

Sorry for the simple question.  Seems I can't use my Perl oneliners at work anymore... but I can use Powershell...  So before i try to learn it....

So.. can i use powershell to write one liners that would do this:

print our line in a text file that only start with 2 tab characters

List from a text file all lines where pos 5-6 has value AB

count the number of blank lines in a text file

replace in a file the string GOO with the string GAA

Remove from a text file all double CRLFs.. (A VBA thing I'm assuming you all know)

ETC ETC.

 Thanks!
