我有一堆日志文件.我需要找出所有文件中出现字符串的次数.
grep -c string *
回报
...
file1:1
file2:0
file3:0
...
使用管道我只能获得具有一个或多个出现次数的文件:
grep -c string * | grep -v :0
...
file4:5
file5:1
file6:2
...
我怎样才能得到合并计数？(如果它返回file4:5, file5:1, file6:2,我想回来8.)
我前段时间在github上分叉了一个存储库,进行了一些小改动并将更改推回到我的github fork.原来的存储库已经改变了.我想将原始存储库中的更改合并到我的fork中.
我是git和github的新手,我需要具体的命令如何做到这一点.
我有一个选择列表:
<select id="filter">
<option value="Open" selected="selected">Open</option>
<option value="Closed">Closed</option>
</select>
当我选择Closed页面重新加载时.在这种情况下,它显示已关闭的票证(而不是打开).我手动操作时工作正常.
问题是当我Closed用Watir选择时页面不会重新加载:
browser.select_list(:id => "filter").select "Closed"
这通常意味着不会触发某些JavaScript事件.我可以用Watir发射事件:
browser.select_list(:id => "filter").fire_event "onclick"
但我需要知道要开火的事件.
有没有办法找出为元素定义了哪些事件？
我有一个排序数组:
[
'FATAL <error title="Request timed out.">',
'FATAL <error title="Request timed out.">',
'FATAL <error title="There is insufficient system memory to run this query.">'
]
我想得到这样的东西,但它不一定是哈希:
[
{:error => 'FATAL <error title="Request timed out.">', :count => 2},
{:error => 'FATAL <error title="There is insufficient system memory to run this query.">', :count => 1}
]
我刚收到此错误消息:
...
from c:/ruby/lib/ruby/gems/1.8/gems/...
... 10 levels...
from c:/ruby/lib/ruby/gems/1.8/gems/...
...
并且bug(当然)隐藏在某处... 10 levels....
如何强制ruby显示完整的堆栈跟踪？
我从Jenkins 网站下载了Mac OS X本机包,安装它,在http:// localhost:8080 /打开我的浏览器,并获得了包含以下文本的错误页面:

我已经在Windows 2008 32位上通过Git/SSH成功克隆了Jenkins中的Git存储库.当我尝试在Windows 2008 64位上执行相同操作时,控制台输出页面卡在此处:
