Trouble passing array to AWS CLI filter

Running the command:

$sgs = @("sg1", "sg2", "sg3")
aws ec2 describe-network-interfaces --filters Name=group-id,Values=$sgs --output json | ConvertFrom-Json

But the CLI doesn't filter by the security group ids. Any help?

Hello.

I assume you are probably using PowerShell since you are using "ConvertFrom-Json".
So please try as follows.

$sgs = @("sg1", "sg2", "sg3")
aws ec2 describe-network-interfaces --filters Name=group-id,Values=$($sgs -join ',') --output json | ConvertFrom-Json

Added "-join" to join "$sgs" passed in an array. By doing this, a string combined in the form "sg1,sg2,sg3" will be passed to "Values". https://learn.microsoft.com/en-us/powershell/scripting/learn/deep-dives/everything-about-arrays?view=powershell-7.4

"Unknown options: -join, ',')" When I run with this command it seems there is a syntax error.

Managed to get this working thanks! --filters "Name=group-id,Values=$($sgs -join ',')"

Try this

sgs=("sg1" "sg2" "sg3")
aws ec2 describe-network-interfaces --filters "Name=group-id,Values=${sgs[*]}" --output json | jq .

This is invalid powershell, see how you were trying to interpolate the array in a string.
