I want to write a variable out but delete the top 3 lines-CodePudding

I am trying to write a powershell script to check all of the online computers and then make it one neat column Here is the code I have so far...

$computers = get-adcomputer -LDAPFilter "(Name=SDA000*)" | Select-Object -Property Name 

$computers1 =  get-adcomputer -LDAPFilter "(Name=SDA005*)" | Select-Object -Property Name 

$computers2 =  get-adcomputer -LDAPFilter "(Name=SDA006*)" | Select-Object -Property Name 

$computers3 =  get-adcomputer -LDAPFilter "(Name=SDA007*)" | Select-Object -Property Name 

$computers4 = ($computers)   ($computers1)   ($computers2)   ($computers3)

[array]$online = @($computers4.Name | % {test-connection -erroraction silentlycontinue -Count 1 $_}) 

$wIw = $online | Select-Object Address

$wIw

But the output always leaves the top 3 lines with extraneous data I don't want. i.e

Address
-------
SDA0003
SDA0007
SDA000B
SDA000C
SDA0050
SDA0051
SDA0054
SDA0057
SDA005F
SDA0061
SDA006B
SDA006D
SDA0076

I can write it to a text file and then pipe it to select-object -skip 3, but that does not seem to work with a variable.

thanks for any advice.

What you are seeing is the header (e.g. the "Address" property). To output it to the screen without the header, you can use the -HideTableHeaders in a Format-Table command:

...
$wIw = $online | Select-Object Address

$wIw | Format-Table -HideTableHeaders

Ohh yes, that treat is sometimes quit helpful but most of the time it is in the way. Here is how I get rid of it:

$computers = (get-adcomputer -LDAPFilter "(Name=SDA000*)" | Select-Object -Property Name).name
