Code Answer: How to zip/unzip files in Powershell?

I'm looking for an one-liner that will zip/unzip files (*.zip) in powershell

From serverfault BlueGene

You may wish to check out http://www.codeplex.com/Pscx which has cmdlets specifically for this.

marc_s : +1 PSCX is a great set of add-on cmdlets - I just wish I could pick and choose more which ones I want and which I don't. It seems to be changing a whole lot in my Powershell instance....

DotNetZip will allow you to do this from Powershell

Not a one-liner but the library will allow you to write the Powershell script you need.

You can also use the COM interface

Of course, I found this by googling "zip powershell" or "unzip powershell". Might want to try that as a resource too.

I find the simplest solution to just use infozip binaries which I have used for years and use in a UNIX environment.
```
PS> zip -9r ../test.zip * 
PS> cd .. 
PS> unzip -t test.zip Archive:  test.zip
    testing: LinqRepository/          OK
    testing: LinqRepository/ApplicationService.cs   OK
    testing: LinqRepository/bin/      OK 
... 
No errors detected in compressed data of test.zip.
```
It would be straighforward to put a powershell wrapper around the text output but in practice I never need that so I haven't bothered.
