I'm new to Powershell as well as scripting (to a degree), and I'm in need of
some advice:

Here's my code:



$sourcedir = "\\SourceServer\usersdir\"
$destdir1 = "\\TargetNode1\usersa-h\"
$destdir2 = "\\TargetNode1\usersi-l\"
$destdir3 = "\\TargetNode2\usersm-p\"
$destdir4 = "\\TargetNode2\usersq-v\"
$destdir5 = "\\TargetNode3\usersw-x\"
$dirlist = get-childitem -path $sourcedir\* -Name
$dirlist |foreach-Object { robocopy.exe $sourcedir$_ '
$destdir$_ /E /XO /R:3 /W:3 /NP /TEE /Log+:d:\RoboLogs\Userdata\$_.txt }

I want to validate that the directory name starts with the letters (in the
groups) a-h or i-l or m-p or q-v or w-x and then write to the appropriate
destdir....

How do I validate the 1st letter of $_ ??

I know about [a-h] grouping, but I'm not sure of the validation of the 1st
letter of a string (i.e. $_ in this case).
Thanks,

Peter

if ($_.name -match "^[a-h]")

Maybe something like this [untested].


$sourcedir = "\\SourceServer\usersdir\"
$dirlist = get-childitem -path $sourcedir\* -Name
$dirlist |foreach-Object { switch ($_.substring(0,1))
{
[a-h] {$destdir = "\\TargetNode1\usersa-h\"}
[i-l] {$destdir = "\\TargetNode1\usersi-l\"}
[m-p] {$destdir = "\\TargetNode2\usersm-p\"}
[q-v] {$destdir = "\\TargetNode2\usersq-v\"}
default {$destdir = "\\TargetNode3\usersw-x\"}
}
robocopy.exe $sourcedir$_ '
$destdir$_ /E /XO /R:3 /W:3 /NP /TEE /Log+:d:\RoboLogs\Userdata\$_.txt
}

Thank you for your assistance... now for the harder part.... I need to
actually understand the code.. ;-)

It's really appreciated...

thanks for the help... I'll work on the code translation....

So is this actually valid $.beginswith ????

There's plenty of help available, for the switch statement see:

Sorry, your top posting makes it difficult to decide
what you are referring to?

If you have scripting experience with vbscript this url might
help with the transition to powershell:
