PowerShell cmd to zip up a directory while excluding multiple subdirectories

Make-Zips.ps1

ls -rec | ? {-not ($_.FullName -match '\\(NUnitConsole|TestRun)\\')} | write-zip -output "$(datefn).zip"

#### If you want to get fancier...

# (1) Make a list of files touched in the last hour.

$fs = ls c:\work\sxa\18.4cu2\Projects\VisitRecord\VRDotNet\Portal\SXA.VR.Portal\bin `
  | ? {$_.LastWriteTime -ge (Get-Date).AddMinutes(-60)}
  
# (2) Add to it.  The '+=' operator actually makes a new Array by copying the old Array + the entry(ies).
#     This is how you get another file, even if it wasn't touched in the last hour.

$fs += (ls c:\work\sxa\18.4cu2\Projects\VisitRecord\VRDotNet\Portal\SXA.VR.Portal\Views\Home\Index.cshtml)

# (3) Zip it all up, sans directory structure.  Write-Zip is from PSCX.  Sadly, its -Append option seems to be broken,
#     so we have to build our list BEFORE we write the zip file.  Oh well, good learning list-management skillz.  :)

pushd c:/tmp
$fs | write-zip -out web-server-dlls.zip -flat -entry /

Apparently, the -exclude option is borked, so we do it with regular expressions.
'datefn' is a function that returns a string timestamp suitable for use as a filename.
