csv - Adding timestamps to every line in output file in Powershell -


i add timestamps test-connection results in output file. importing data csv file contain spot timestamp. create output file using export-csv shown in code snippet below. have tried various methods add timestamps every line in output file no success. latest attempt use filter , pipeline in failed. relatively new powershell please forgive sloppiness. thank in advance help. 

$printerlist = import-csv "printerlist.csv"  $releaselist = import-csv "releasestations.csv"                       #object list rows of csv file $filename = "printlog.csv" $filename2 = "releaselog.csv"                                         #file name log file $printersdown = @()                                                   #string list printers down in email $printersdown += "****************" $printersdown += "* printer down *" $printersdown += "****************" $printersdown += "" $stationdown = @() $stationdown += "****************" $stationdown += "*release station down*" $stationdown += "****************" $stationdown += "" $downflag = 0 $downflag2 = 0                                                         #flag check when send alert email filter timestamp {"$(get-date -format mm_dd_yy_hhmm):$_"}        foreach ($printer in $printerlist){         if(test-connection -count 1 -quiet -computername $printer.ip){             $printer.status = "up"             write-host ("{0}: up" -f $printer.printername)         }else{             write-host ("{0}: down" -f $printer.printername)             $printer.status = "down"             $printersdown += ("{0} : {1}" -f $printer.printername, $printer.ip)             $downflag = 1         }            }     foreach ($station in $releaselist){         if(test-connection -count 1 -quiet -computername $station.releasestation){             $station.status = "up"             write-host ("{0}: up" -f $station.releasestation)         }else{             write-host ("{0}: down" -f $station.releasestation)             $station.status = "down"             $stationdown += ("{0}" -f $station.releasestation)             $downflag2 = 1         }            }   # write csv file  $printerlist | export-csv -append -notypeinformation -path logs\$filename $releaselist | export-csv -append -notypeinformation -path logs\$filename2

you should add timestamp directly objects in lists. if csv has "timestamp" field available that, change objects this:

    foreach ($printer in $printerlist){     if(test-connection -count 1 -quiet -computername $printer.ip){         $printer.status = "up"         write-host ("{0}: up" -f $printer.printername)     }else{         write-host ("{0}: down" -f $printer.printername)         $printer.status = "down"         $printersdown += ("{0} : {1}" -f $printer.printername, $printer.ip)         $downflag = 1     }            $printer.timestamp=(get-date -format mm_dd_yy_hhmm) } foreach ($station in $releaselist){     if(test-connection -count 1 -quiet -computername $station.releasestation){         $station.status = "up"         write-host ("{0}: up" -f $station.releasestation)     }else{         write-host ("{0}: down" -f $station.releasestation)         $station.status = "down"         $stationdown += ("{0}" -f $station.releasestation)         $downflag2 = 1     }            $station.timestamp=(get-date -format mm_dd_yy_hhmm) }

should do. should work because export-csv enumerates fields in lists supplied, , since objects have field, exported properly.
