How can I embed some HTML in a shell script?
提问by par181
I want to include some HTML in a shell script. This is what I've tried:
我想在 shell 脚本中包含一些 HTML。这是我尝试过的：
(
echo "<html>
<head>
<title>HTML E-mail</title>
</head>
<body>
<p style="font-family:verdana;color:red;">
This text is in Verdana and red</p>
</body>
</html>"
)>pkll.htm
However, instead of writing the HTML to file, it gives me some errors:
但是，它没有将 HTML 写入文件，而是给了我一些错误：
> bash: color:red: command not found bash: > This text is in Verdana and
> red</p </body> </html>: No such file or directory
How can I do this?
我怎样才能做到这一点？

A better option would be to use the here document syntax (see this answer):
更好的选择是使用 here 文档语法（请参阅此答案）：
cat << 'EOF' > pkll.htm
<html>
<head>
<title>HTML E-mail</title>
</head>
<body>
<p style="font-family:verdana;color:red;">
This text is in Verdana and red
</p>
</body>
</html>
EOF
Your attempt failed because the double quotes in the HTML terminates the double quotes you wrapped around it and causing the <>s to be seen as redirections and the ;s to terminate the echocommand.
您的尝试失败了，因为 HTML 中的双引号终止了您环绕它的双引号，并导致<>s 被视为重定向，而;s 终止了echo命令。
You could technically have used single quotes:
从技术上讲，您可以使用单引号：
(
echo '<html>
<head>
<title>HTML E-mail</title>
etc ...'
)>pkll.htm
but then you just have the same problem again if the HTML contains a ', such as an apostrophe or in an attribute. The here document has no such issues.
但是，如果 HTML 包含'，例如撇号或属性，您就会再次遇到相同的问题。这里的文档没有这样的问题。

You need to escape the quote in the html, because you have a quote on the start of the argument to echo.
您需要对 html 中的引号进行转义，因为您在要 echo 的参数的开头有一个引号。
Your terminal interprets it as
您的终端将其解释为
<html>...<p style="
first argument
第一个论点
font-family:verdana;
as second argument, and the rest as other commands because you have a semicolon.
作为第二个参数，其余的作为其他命令，因为你有一个分号。
So you need to replace the p tag into
所以你需要把p标签替换成
<p style=\"font-family:verdana;color:red;\">
