Sorry if the title is not very self-explanatory, I am trying to run an ssh
command with ProxyCommand
in one line:
ssh -i /home/myuser/.ssh/myprivatekey.pem ec2-user@i-00xxxxxxxxxx -o ProxyCommand="aws ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"
This command above works, however I need to do the same in go.
func (s SSH) Tunnel() error {
parts := strings.Fields(`ssh -i /home/myuser/.ssh/myprivateksy.pem ec2-user@i-00xxxxxxxxxxx`)
parts = append(parts, `-o ProxyCommand="aws ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"`)
command := exec.Command(parts[0], parts[1:]...)
command.Stderr = os.Stderr
command.Stdout = os.Stdout
command.Stdin = os.Stdin
return command.Run()
}
However I got this error:
zsh:1: command not found: aws ssm start-session --target i-00Xxxxxxxxxxxx --document-name AWS-StartSSHSession --parameters 'portNumber=22'
I have tried to include it in the strings.Fields
:
parts := strings.Fields(`ssh -i /home/myuser/.ssh/myprivateksy.pem ec2-user@i-00xxxxxxxxxxx -o ProxyCommand="aws ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"`)
However with this I have another error:
zsh:1: unmatched "
How can I achieve this?
Thanks

Based on the shell input you gave, the following should work:
parts := strings.Fields(`ssh -i /home/myuser/.ssh/myprivateksy.pem ec2-user@i-00xxxxxxxxxxx -o`)
parts = append(parts, `ProxyCommand=aws ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'`)
This will pass the part that comes after -o
as a single argument without the quotes. Shell processing would remove those quotes.
