我正在尝试以另一个用户身份运行命令并以该用户身份读取输入.由于某种原因,脚本不会暂停read命令,我不确定为什么.这是脚本的一个例子:
#!/bin/bash
username='anthony'
sudo -H -u "$username" bash << 'END_COMMAND'
# Commands to be run as new user
# -------------------------------
echo "#! Running as new user $USER..."
echo "#! Gathering setup information for $USER..."
echo -n "Enter your name and press [ENTER]: "
read name
echo -n "Enter your email and press [ENTER]: "
read email
END_COMMAND
echo "Done"
关于为什么这不停止read name或任何想法read email？
我正在尝试使用Selenium(在Python中)从网站中提取一些信息.我一直在选择带有XPath的元素,但是在使用以下兄弟选择器时遇到了麻烦.HTML如下:
<span class="metadata">
<strong>Photographer's Name: </strong>
Ansel Adams
</span>
我可以选择"摄影师的名字"
In [172]: metaData = driver.find_element_by_class_name('metadata')
In [173]: metaData.find_element_by_xpath('strong').text
Out[173]: u"Photographer's Name:"
我正在尝试选择标记后的文本部分(示例中为"Ansel Adams").我假设我可以使用以下兄弟选择器,但我收到以下错误:
In [174]: metaData.find_element_by_xpath('strong/following-sibling::text()')

文件1:

self.name = name
self.count = 0
def __string__(self):
message = self.name + self.count

我可以跑./configure,make没有问题. ./configure以..结束:
