python的子进程（调用或popen）在终端中工作，但在Gnome Schedule User Guide V2.2中不工作

我试图从python（2.75）脚本调用wget：

它可以在IDE（eclipse）中正常工作，也可以在终端中正常工作，但是当我尝试从Gnome Schedule User Guide V2.2运行它时，我得到以下结果：

--2013-08-16 11:27:35--  https://192.168.0.1/003/

…因此，它似乎没有使用命令“wget arg1 arg2 arg3…”，而是尝试运行： “wget arg1” “wget arg2” “wget arg3”

当从调度程序运行时，有什么线索可以产生不同的结果吗

我在计划程序中使用的命令是： “python/home/python/Download/Download.py”

谢谢

我自己解决了这个问题，将第二个参数移到了最后一个位置：

cmd = ['wget', '--tries=5', '--http-user=foo', '--http-passwd=bar', '--auth-no-challenge', '--no-check-certificate', '--output-document=temp/page.html', 'https://192.168.0.1/003/']

它现在可以工作了，但我仍然想知道为什么在终端或IDE中它工作得很好，而不是从调度程序运行时

cmd = ['wget', '--tries=5', '--http-user=foo', '--http-passwd=bar', '--auth-no-challenge', '--no-check-certificate', '--output-document=temp/page.html', 'https://192.168.0.1/003/']
