I would like a Powershell equivalent of the following script

I would like to convert the following script in Powershell.


Set fso = CreateObject("Scripting.FileSystemObject")

data = Split(fso.OpenTextFile("output.ed").ReadAll, "AIS*00*")
For i = 1 To UBound(data)
  fso.OpenTextFile("new" & i & ".txt", 2, True).Write "AIS*00*" & data(i)
Next

Being that split uses a regular expression the above won't work as it is expecting 0 or more repetitions of 'S' and '0', not 'S*' and '0*'. You will want to make sure you escape the asterisk/star.

(gc "$path\output.ed") -split "AIS\*00\*" | %{

Did not look at the search string :)

I can generalize the script so it does not matter if there are special characters in it:

###REPLACE WITH YOUR OWN DATA###
$path = "X:\your\path"
$searchString = "AIS*00*"
$i = 1

###DO NOT MODIFY BELOW###

$searchString = [regex]([regex]::Escape($searchString))
(gc "$path\output.ed") -split $searchString | %{ 
    New-Item -ItemType file -Path "$path\new$i.txt" -Value "$searchString$_" -Force
    $i++
}

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Thanks Dan.  The script does not seem to work well, it created many .txt files when in fact the data I was using had only 2 sets of data.  Also all the txt files seem to be one liners etc..

OK. Please attach a sample file, so I can test on your data.

Thanks Learnctx.  
This script does not work, it produces this issue:



Missing closing '}' in statement block.
At C:.....1:1 char:47

There was a missing the parameter: raw. Without it, get-content gets one line at a time
###REPLACE WITH YOUR OWN DATA###
$path = "X:\your\path"
$searchString = "AIS*00*"
$i = 1

###DO NOT MODIFY BELOW###

$searchString = [regex]([regex]::Escape($searchString))
(gc "$path\output.ed" -Raw) -split $searchString | %{ 
    New-Item -ItemType file -Path "$path\new$i.txt" -Value "$searchString$_" -Force
    $i++

There seems to be an error in the get-content parameter names evaluation, at least for me (PS 4). I had to put -Raw as first switch / parameter to get it work:
 (gc -raw "$path\output.ed") -split $searchString | %{

I cannot prove http:#a40342021 - getting that error is probably due to changes you made we do not see.

Dan CraciunIT ConsultantCommented:
Weird. I'm on PS4 also (win 8.1) and it worked with -raw at the end.

Dan CraciunIT ConsultantCommented:
@Qlemo: I don't think the OP did any changes. He simply used that line (
(gc "$path\output.ed") -split "AIS\*00\*" | %{
) and the parser complained it found an opening curly brace without a matching closing one.
0
QlemoBatchelor, Developer and EE Topic AdvisorCommented:
This is valid syntax. The parser knows there has to be more on following lines. It won't complain (yet) about a curly brace mismatch.
0
Dan CraciunIT ConsultantCommented:
It will, if you paste the line in the PS console:
Missing closing '}' in statement block.

Not in PS ISE on my computer:

QlemoBatchelor, Developer and EE Topic AdvisorCommented:
Ahh, using ISE. Important point to know. Yes, the ISE prompt will require "complete" code, because it runs line by line, not allowing for splitting code over several lines.

Note: Don't try multi-line code in the ISE's PS Console, because it is not the same as in the script window or the non-ISE PowerShell prompt.
0
Dan CraciunIT ConsultantCommented:
You just can't write multi-line code in ISE's PS Console. But pasting multiple lines of code works just fine.

Then again, in ISE you have a window above where to write the code...

QlemoBatchelor, Developer and EE Topic AdvisorCommented:
That's the point - there is no point in pasting it into the Console part :D
0
Dan CraciunIT ConsultantCommented:
You have to save the code to be able to run it from the script pane.

For a quick throwaway script it's faster (for me) to write it in the script pane and then just paste it in the console and run it.

Using PowerGUI, so not having those issues. It runs unsaved scripts with temporary names, and I don't have to bother about anything :p
