我想从缩小的html文件中删除所有外部js调用。但是,如果js调用位于另一行中,则以下内容将删除(不适用于缩小的html)
var=$(sed -e '/^<script.*<\/script>$/d' -e '/.js/!d' testFile.html)
grep -v "$var" "testFile.html" | sponge "testFile.html"
样本输入文件:
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>JavaScript Ders 2</title> <script type="text/javascript" src="script.js" language="javascript"></script> <script></script> </head><body></body></html>
示例输出文件:
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>JavaScript Ders 2</title> <script></script> </head><body></body></html>
预先感谢

不幸的是,sed不支持非贪婪/惰性匹配。试试perl:
perl -pe 's/<script.*?script> //'
