How to use variable for invoke-ssh

[ganapa2000]

Hi,

I am trying to update user names on multiple VMs. the below script is not working. how can I use the below script with variable so that I can mention or import through a csv input.

Please help.

$serv = "mytestvm"
$myuser = "johnb"
$Username = 'root'
$session = New-SSHSession $serv
$connected = $session.Connected
Invoke-SSHCommand -SSHSession $session -Command 'sed -i "s/.*pam.allow.users:.*/&,$($myuser)/" /etc/centrifydc.conf'
Remove-SSHSession $session -Verbose | Out-Null

You can use the ExpandString method, see Here strings and the ExpandString method - LucD notes

That worked. Thank you very much LucD

$serv = "mytestvm"
$myuser = "johnb"
$mycommand = @'
sed -i "s/.*pam.allow.users:.*/&,$myuser/" /etc/centrifydc.conf
'@
$Username = 'root'
$session = New-SSHSession $serv
$connected = $session.Connected
$cmdSub = $ExecutionContext.InvokeCommand.ExpandString($mycommand)
Invoke-SSHCommand -SSHSession $session -Command $cmdSub
Remove-SSHSession $session -Verbose | Out-Null
