Let's say I have a string like this

It's not particularly pretty, but perhaps something like ....

$a = "aabbcc"
for ($i = 0; $i -le ($a.length-1); $i += 2) {"$($a[$i])$($a[$i+1])"}

Also:
$str = 'aabbcc'

# v1
[regex]::split($str, '(.{2})') | ? {$_}

# v2
$str -split '(.{2})' | ? {$_}

Hi Jon. Thanks for your reply. It works perfectly but i have to split a string of thousands chars.
Now I try to explain exactly my problem.

I have a file like this
string1of16chars
string2of16chars
string3of16chars
string4of16chars
string5of16chars
string6of16chars

and so on.

I have to join these lines grouping them three by three.
So the first line become

string1of16charsstring2of16charsstring3of16chars

the second
string4of16charsstring5of16charsstring6of16chars

and so on

I don't know how to solve this problem. Using add-content I've created a kilometric one-line string and now I was looking for a way to split every 48 chars but maybe with a loop it's possible to join the lines three by three.

Thanks again.

A slight variation of Kiron's earlier suggestion would probably work better
than my looping construct eg

$str = "<your superlong combined string>"
[regex]::split($str, '(.{48})') | ? {$_}

Something like this might be a looping solution, though
eg if such a large string proved too cumbersome etc....

#-----------------------------------------
$wholefile = Get-Content "C:\temp\RawData.txt"
$Combinations = [int]($wholefile.length /3 )

foreach ($Set in 1..$Combinations) {

$Set1 = $wholefile[$(($Set-1)*3)].Trim()
$Set2 = $wholefile[$((($Set-1)*3)+1)].Trim()
$Set3 = $wholefile[$((($Set-1)*3)+2)].Trim()

"$($Set1)$($Set2)$($Set3)"

}

Oh my god, this powershell rulez.
Thanks Kiron. I didn't see your reply before. I spend a lot of time trying to write a comprehensible english. Maybe I was still writing when you posted.
Your solution is perfect.

Just another question if I can.
Your second solution doesn't work on my powershell.
I deduce I've version 1.
I've found this link
Download details: Windows PowerShell 2.0 CTP

but I don't know what to do.
Do I have to uninstall my powershell 1 or not?
Thanks for your patience and thanks even to Jon.
I love this forum.

You can install that one, but this is the most recent version I think ...


Windows PowerShell V2 Community Technology Preview 2 (CTP2)
http://www.microsoft.com/downloadS/d...displaylang=en

Yeah, you need to uninstall Powershell 1 first.

Wow. Fantastic Jon. Thank you very much.
In a single thread I've seen a lot of interesting thing.
Compliments for your knowledge and your kindness.

> I have to join these lines grouping them three by three.

Use the -ReadCount parameter (and set $OFS to whatever text you want as the
separator between lines). For your case, if an example file test.txt has
these six lines:

A1A2A3A4A5A6A7A8
B1B2B3B4B5B6B7B8
C1C2C3C4C5C6C7C8
D1D2D3D4D5D6D7D8
E1E2E3E4E5E6E7E8
F1F2F3F4F5F6F7F8

Then we run a command like this:

> $ofs="";
> get-content C:\Users\Joel\test.txt -readcount 3 | ForEach-Object { "
> OUTPUT: '$_' " }

OUTPUT: 'A1A2A3A4A5A6A7A8B1B2B3B4B5B6B7B8C1C2C3C4C5C6C7C8'
OUTPUT: 'D1D2D3D4D5D6D7D8E1E2E3E4E5E6E7E8F1F2F3F4F5F6F7F8'

That's what you want, right?
