Question

Forgive the novice question, i’m new to powershell and am trying to do something which should be very easy!

i have a text file with the following contents

DEVICE ID:   {E24CF707-F030-48DC-8E1A-59B96148BF52}
DEVICE NAME: All Devices (RAINBOW-SRV)
TYPE:        Drive pool
DEVICE ID:   {D16DC75F-8A8B-4AEC-A411-9B0BC58CBF16}
DEVICE NAME: HP 1
TYPE:        Drive
DEVICE ID:   {F2D2AB4A-1FBE-4158-AB62-6A94AE4392E2}
DEVICE NAME: RAINBOW-SRV
TYPE:        Machine
DEVICE ID:   {23AD5D42-00A8-496B-96E5-1F5CAA3F9E9D}
DEVICE NAME: Symantec Protection Network (RAINBOW-SRV)
TYPE:        Symantec Protection Network
RETURN VALUE: 1

I’m trying to get the string that follows DEVICE NAME: on each occurence into an array to pass to a command further down the line. I’ve tried the following code but get an error stating that Substring is not a valid method.

I feel i’m missing something very obvious but cannot see it! any help would be much appreciated.

Many Thanks

Read the file content, filter the lines that begins with ‘DEVICE NAME: ‘, for each line remove (replace with nothing) ‘DEVICE NAME: ‘

Get-Content devices.txt | Where-Object {$_ -like 'DEVICE NAME:* '} | Foreach-Object {$_ -repla
ce '^DEVICE NAME: '}

All Devices (RAINBOW-SRV)
HP 1
RAINBOW-SRV
Symantec Protection Network (RAINBOW-SRV)

UPDATE: per OT request, how to pass the value to an executable command

Get-Content devices.txt | 
Where-Object {$_ -like 'DEVICE NAME:* '} | 
Foreach-Object {
    $device = $_ -replace '^DEVICE NAME: '
    app.exe "$device"
}
