如果行有引号，则sed命令失败 [英] sed command fails if line has quote

问题描述

我正在尝试创建一个脚本来搜索文件列表并删除

以下行


< meta http-equiv = QUOT;内容类型"含量=" text / html的; charset =<？php echo

CHARSET; ？>">


我这样做是通过生成一个sed命令并使用系统执行

就像这样：


$ t = sprintf（"％s \" s /< meta http-equiv =" Content-Type" content =" text / html;

charset =<？php echo CHARSET;？>">％s / g \"％s>％s"，$ sedPath，$ str1_rpl，

$ infile，$ outfile）;

system（$ t）;


问题是要替换的文本中的引号。 sed认为它是b / b
作为其命令的一部分而忽略了它之后的一切。例如，如果我使用

< meta http-equiv =" Content-Type" content =


搜索字符串，它有效。但是，如果我使用

< meta http-equiv =" Content-Type" content ="


它不起作用。我试过逃避报价（\）但是没有帮助。


有没有人对我还能尝试什么有任何建议？

解决方案

t = sprintf（"％s \" s /< meta http-equiv =" Content-Type" content =" text / html ;

charset =<？php echo CHARSET;？>">％s / g \"％s>％s"，

< blockquote> sedPath，

str1_rpl，

I''m trying to make a script that will search a list of files and remove
the following line

<meta http-equiv="Content-Type" content="text/html; charset=<?php echo
CHARSET; ?>">

I''m doing this by generating a sed command and using system to execute
it like so:

$t = sprintf("%s \"s/<meta http-equiv="Content-Type" content="text/html;
charset=<?php echo CHARSET; ?>">%s/g\" %s >%s", $sedPath,$str1_rpl,
$infile, $outfile);
system($t);

The problem is the quote found in the text to be replaced. sed sees it
as part of its command and ignores everything after it. For example, if
I use
<meta http-equiv="Content-Type" content=

for the search string, it works. But if I use
<meta http-equiv="Content-Type" content="

it doesn''t work. I have tried escaping the quote (\")but that didn''t help.

Does anyone have any suggestions as to what else I could try?

解决方案

t = sprintf("%s \"s/<meta http-equiv="Content-Type" content="text/html;
charset=<?php echo CHARSET; ?>">%s/g\" %s >%s",

sedPath,

str1_rpl,
