当我定义要在多个远程服务器上运行的任务时,如果任务在服务器1上运行并退出并出现错误,则Fabric将停止并中止该任务.但是我想让Fabric忽略错误并在下一个服务器上运行任务.我该怎么做呢？
例如:
$ fab site1_service_gw
[site1rpt1] Executing task 'site1_service_gw'
[site1fep1] run: echo 'Nm123!@#' | sudo -S route
[site1fep1] err:
[site1fep1] err: We trust you have received the usual lecture from the local System
[site1fep1] err: Administrator. It usually boils down to these three things:
[site1fep1] err:
[site1fep1] err: #1) Respect the privacy of others.
[site1fep1] err: #2) Think before you type.
[site1fep1] err: #3) With great power comes great responsibility.
[site1fep1] err: root's password:
[site1fep1] err: sudo: route: command not …我正在使用子进程模块调用外部程序(plink.exe)来登录服务器; 但是当我呼叫通信来读取输出时,它就是阻塞.代码如下:
import subprocess
process = subprocess.Popen('plink.exe hello@10.120.139.170 -pw 123456'.split(), shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
print process.communicate() #block here
我知道该块是因为plink.exe它仍在运行; 但我需要在子进程终止之前读取输出.反正有吗？
当我在emacs中使用dired模式时,我可以按类型!xxx运行shell命令,但是如何绑定一个键来运行这个命令？例如,我想在文件上按O,然后dired将运行'cygstart'来打开这个文件.
在emacs中,如果选择了区域,我想将Ck绑定到kill-region; 其他杀线正常.如何配置？
rss文件如下所示，我想在media：group部分中获取内容。我检查了feedparser的文档，但似乎没有提及。怎么做？任何帮助表示赞赏。
