Question

我试图从我的python（2.75）脚本调用wget：

cmd = ['wget', 'https://192.168.0.1/003/', '--tries=5', '--http-user=foo', '--http-passwd=bar', '--auth-no-challenge', '--no-check-certificate', '--output-document=temp/page.html']
proc = subprocess.Popen(cmd)
# same with subprocess.call(cmd)

它在IDE（eclipse）中工作正常，也在终端中，但是当我尝试从Gnome Schedule User Guide V2.2运行它时，我得到以下内容：

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

...所以不是采取命令“wget arg1 arg2 arg3 ...”，它似乎试图运行： “wget arg1” “wget arg2” “wget arg3” ...

从调度程序运行时可能产生不同结果的任何线索？

我在调度程序中使用的命令是： “python /home/python/Download/Download.py”

我自己通过移动最后一个位置的第二个参数来解决它：

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/']

它现在有效，但我仍然想知道为什么在终端或IDE中它运行良好而不是从调度程序运行时...

python，subprocess（call或popen）在终端中工作，但在Gnome Schedule User Guide V2.2中不起作用
