Is there a way to correctly append a string before an array index? For some reason there is space added before $ips on the output.

$ips=50..61;$vms=10..21;$i=0;$vms |%{
write-host New-VMHostNetworkAdapter -VMHost bsesx0"$vm"v.abc.com -VirtualSwitch vswitch0 -PortGroup "vmk1" -IP "10.1.1."$ips[$i] -SubnetMask 255.255.255.0 -VMotionEnabled:'$true';$i++
}

Open in new window


Output -
New-VMHostNetworkAdapter -VMHost bsesx021v.bbh.com -VirtualSwitch vswitch0 -PortGroup vmk1 -IP 10.1.1. 61 -SubnetMask 255.255.255.0 -VMotionEnabled: $true

Try
"10.1.1.$($ips[$i])"

It works but why there is a space between the string and variable if I use the following?

Is $() going to work on any variable?

"10.1.1."$ips[$i]

You can also use 10.1.1.$($ips[$i]). Because these characters are not recognized as a valid expression and PowerShell consider it as an expandable string and pass it to Write-host.

When you use "10.1.1.$($ips[$i])”, again PowerShell consider it as a single expandable string since both the 10.1.1. and var is inside the double quotes.

When you use "10.1.1."$ips[$i], it become two valid expressions. So PowerShell interpret it as two separate expressions before passing them to Write-Host and Write-Host separates them with a separator.

Thanks! Sometimes I found explanation is more important than solution.
