    Hi,

    I'm trying to change the format of a variable in my script.  I'd like to change a variable from this

    $Name = "Thistext-11.11.11-moretext"

    I want to change the text to something like this in a new variable

    "11_11_11differenttext"

    I've got most of it working

    $New = $VMName -replace "Thistext-","" -replace "-moretext",""

    result is "11.11.11"

    If I try to replace the "."  the result is "_______"

    $New = $VMName -replace "Thistext-","" -replace "-moretext","" -replace ".","_"

    TIA

    I got it working with the following. For some reason it doesn't work as a single line but this is fine.

    $ISOname = "text-11.2.111-moretext"
    $New = $ISOname -replace "text-","" -replace "-moretext","" -replace "\.","\_" -replace "\\",""
    $VMName = "Newtext_"+$VMName+"_morenew"

    So the output is

    Newtext_11_2_111_morenew

    Two methods can be used.

    'Thistext-11.11.11-moretext' -replace 'Thistext-'
('Thistext-11.11.11-moretext' -split '-')[1..2] -join ''

    But, if you want the numbers then we would do this:

    'Thistext-11.11.11-moretext' -replace '.*-(\d+\.\d+\.\d+).*','$1'

    To replace the dots we would do this:

    'Thistext-11.11.11-moretext' -replace '.*-(\d+\.\d+\.\d+).*','$1' -replace '\.'

    I'm not sure why you couldn't get it to work.

    $ISOname = "text-11.2.111-moretext"
$VMName = $ISOname -replace '^.+(\d+)\.(\d+)\.(\d+).*$','Newtext_$1_$2_$3_morenew'
