PowerShell and Robocopy part 1
listening to the PowerScripting Podcast - Episode 41 RoboCopy was mentioned, and I remembered some Robocopy stuff I still had laying around :
And I will use it as a series about using / wrapping a native tool from PowerShell, I start out with a bit of Text Processing,
#############################################################################################
## Make RoboCopy Help Object
#############################################################################################
$RoboHelp = robocopy /? | Select-String '::'
$r = [regex]'(.*)::(.*)'
$RoboHelpObject = $RoboHelp | select `
@{Name='Parameter';Expression={ $r.Match( $_).groups[1].value.trim()}},
@{Name='Description';Expression={ $r.Match( $_).groups[2].value.trim()}}
$RoboHelpObject = $RoboHelpObject |% {$Cat = 'General'} {
if ($_.parameter -eq '') { if ($_.Description -ne ''){
$cat = $_.description -replace 'options :',''}
} else {
$_ | select @{Name='Category';Expression={$cat}},parameter,description
}
}
This peice of PowerShell code basically just starts Robocopy /? , parses the resulting help text into an Custom object, this gives us a Robocopy help object in the variable $RoboCopyHelpObject and we can check it like this :
You can see that as I have the robocopy help in object form now I can do for example grouping and counting of the Help topics,
I did a series about TextScraping where you can find more examples of text to object translations, so I won't go into much detail here but we will use this object we created later in this series.
Enjoy,
