PowerShell - iterating over computer names in Active Directory -

-

i'm new powershell , i'm attempting write script query ad machine names, check ones responding , write output file. far have this:

$computers = get-adcomputer -filter {(name -like "pc*")} | select-object -property name foreach ($computer in $computers) {     if((test-connection -cn $computer -buffersize 16 -count 1 -ea 0 -quiet)) {         "machine $computer connected." | out-file "out.txt" -append     } else {         "machine $computer not connected." | out-file "out.txt" -append     } #end if } #end foreach

what in output text file looks following:

... machine @{name=pc-0649} not connected. machine @{name=pc-1541} not connected. machine @{name=pc-1574} not connected. ...

i think problem lies select-object -property name part of first line. running debugger, looks powershell formatting each iteration of $computer include header line.

[dbg]: ps y:\>> $computer  name                                                                                                                                                                                           ----                                                                                                                                                                                           pc-0649

what's best way me strip out except pc-#### part in situation?

i think problem still have list of (truncated) computer objects in $computers. verify doing $computers[0].gettype(). if don't see string, it's not string. :) try instead:

$computers = get-adcomputer -filter {(name -like "pc*")} |     select-object -expandproperty name
