提升一个函数的权限(linux)

import std.stdio;
import std.process;
import std.format;
import std.algorithm;

// Copied the interface from executeShell
auto executeShellSudo(scope const(char)[] command,
                      const string[string] env = null,
                      Config config = Config.none,
                      size_t maxOutput = size_t.max,
                      scope const(char)[] workDir = null,
                      string shellPath = nativeShell) {
  // First assume the user is super user:
  auto suCommand = format!"sudo --non-interactive %s"(command);
  auto execute() {
    return executeShell(suCommand, env, config, maxOutput, workDir, shellPath);
  }

  auto result = execute();

  if ((result.status == 1) &&
      (result.output == "sudo: a password is required\n")) {

    // Have sudo ask for password. (Alternatively, sudo can be invoked
    // with the --askpass switch.)
    suCommand = format!"sudo %s"(command);
    result = execute();
  }

  return result;
}

void main() {
  auto result = executeShellSudo("cat /dev/null");
  writeln(result);
}

windows有执行壳函数在这里
找ShellExecuteA函数.
同样,这里可以找windows的api.

这样:

alias runas = compose!(x => to!bool((cast(int) x) > 32), x => ShellExecute(null, "runas", "cmd", cast(wchar*)`/c "cd /d %s && %s"`.format(getcwd(), x).to!wstring, null, SW_HIDE);
