exec

var ExecCmd = &cobra.Command{
	Use:   "exec [flags] [USER@]SERVER [--] COMMAND...",
	Short: "Execute a command on a remote server",
	Long: `Execute a command on a remote server.

This command executes a specified command on a remote server and returns the output.
It supports SSH-like syntax for specifying the user and server.

Use -- to separate alpacon flags from the remote command, ensuring that flags
intended for the remote command (e.g., -U, -d) are not interpreted as alpacon flags.

All flags must be placed before the server name.

Flags:
  -u, --username [USER_NAME]    Specify the username for command execution.
  -g, --groupname [GROUP_NAME]  Specify the group name for command execution.`,
	Example: `  # Simple command execution
  alpacon exec prod-docker docker ps
  alpacon exec root@prod-docker docker ps

  # Use -- to pass flags to the remote command
  alpacon exec root@db-server -- docker exec postgres psql -U myproject -d myproject
  alpacon exec my-server -- grep -r "pattern" /var/log

  # Specify user and group with flags
  alpacon exec -u root prod-docker systemctl status nginx
  alpacon exec -g docker user@server docker images`,
