Hi All,

   Request your help on how to execute aws commands, below is an 
example code, and this code is not working, tried several options 
nothing seem to be working.

Code:
import std.process: environment, execute;
import std.stdio: writeln;

void main() {
environment["AWS_DEFAULT_REGION"] = "eu-west-1";
auto pid = execute(["/usr/bin/aws ec2 describe-images --filters 
'Name=state,Values=available' --query 'Images[*].[ImageId]'"]);
if (pid.status != 0) { writeln("Failed"); } else { 
writeln(pid.output); }
}

Tried the below(execute, executeShell,spawnProcess,execv)

auto pid = execute(["/usr/bin/aws ec2 describe-images --filters 
'Name=state,Values=available' --query 'Images[*].[ImageId]'"]);

auto pid = execute(["/usr/bin/aws", "ec2 describe-images 
--filters 'Name=state,Values=available' --query 
'Images[*].[ImageId]'"]);

auto pid = execute(["/usr/bin/aws", "ec2 describe-images", 
"--filters 'Name=state,Values=available'", "--query 
'Images[*].[ImageId]'"]);

auto pid = execute(["/usr/bin/aws", "ec2", "describe-images", 
"--filters 'Name=state,Values=available'", "--query 
'Images[*].[ImageId]'"]);

You need to break up your command line so that each argument is 
in a separate array element. In the commands above you have 
multiple arguments grouped together into each array element.

Alternately, you can pass everything in a single string to 
`executeShell`.

Hi Paul,

  Thank you very much was able to execute the aws commands using 
`executeShell`.
