在 foreach 循环中执行 powershell 命令

Question

I am trying to execute aws s3 cp command in Powershell. I have a list of files which I defined in an array-like below.

$filearray = ("file1.txt", "file2.txt", "file3.txt", "file4.txt", "file5.txt")

Now when I am trying to copy these files from s3 using aws s3 cp command nothing works.

$filearray | foreach { "aws s3 cp s3://<bucket_name/path_to_file/$_ . --sse aws:kms --sse-kms-key-id 12345-abcxzd" }

I tried below as well. But it didn't work. Can someone point out the mistake I am doing?

foreach ($element in $filearray) { "aws s3 cp s3://<bucket_name/path_to_file/$element . --sse aws:kms --sse-kms-key-id 12345-abcxzd" }

Now I have added variables to my aws command also which will be like below when the loop executes.

$kms_key_option="--sse aws:kms --sse-kms-key-id 12345-abcxzd" $s3_location="s3://<bucket_name/path_to_file/"

foreach ($element in $filearray) { & aws s3 cp $s3_location/$element $current_location $kms_key_option }

But there is a catch in this. Only the first 2 variables in command block work as variables rest 2 do not work as variables. ie $current_location $kms_key_option So the problem statement is changing here a little bit.

Note: I have aws cli installed on my windows machine it works with normal command but it doesn't work in foreach loop.

您正在寻找 & 运算符。

foreach ($element in $filearray) { & "aws s3 cp s3://<bucket_name/path_to_file/$($element) . --sse aws:kms --sse-kms-key-id 12345-abcxzd" }

Answer 2

I'd say try it without the Quotes in the foreach loops?

foreach ($element in $filearray) {
    aws s3 cp s3://<bucket_name/path_to_file/$element . --sse aws:kms --sse-kms-key-id 12345-abcxzd
}
