The interval is specified using the regex repetition operator, {min,max}. $a = 'abcdefghijklmnopqrstuvwxyz' ([regex]::matches($a, '.{1,3}') | %{$_.value}) -join ' ' ([regex]::matches($a, '.{1,8}') | %{$_.value}) -join '..' ([regex]::matches($a, '.{1}') | %{$_.value}) -join '-' #output abc def ghi jkl mno pqr stu vwx yz abcdefgh..ijklmnop..qrstuvwx..yz a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z Removal of $_ and also $PSItem in PS v3 In PowerShell, the variable "$_" has special importance. It works like a placeholder in scenarios like this one: PS> Get-ChildItem $env:windir | Where-Object { $_.Length -gt 1MB } In PowerShell v3, there is an alias for the cryptic "$_": $PSItem. So now code can become more descriptive: PS> Get-ChildItem $env:windir | Where-Object { $PSItem.Length -gt 1MB } Then again, in PowerShell v3, "$_" isn't necessary in many scenarios anymore at all. You could also write: Get-ChildItem $env:windir | Where-Object Length -gt 1MB Feedback Send us feedback at get [dash] scripting [at] hotmail [dot] co [dot] uk or leave a comment here on the blog Follow us on Twitter and join our Facebook Group http://twitter.com/getscripting http://twitter.com/jonathanmedd http://twitter.com/alanrenouf Get-Scripting Facebook Group Extensive list of Powershell Twitterers
