I want to search for a line that contains log4j and take 7 lines before and 3 lines after the match.
grep -B7 -A3 "log4j" web.xml
After that
I want to add comment tags before this paragraph and after it.
<!--
paragraph that
i found by grep
-->
I wrote this script bellow:
search=`find . -name 'web.xml'`
text=`grep -B7 -A3 "log4j" $search`
sed -i "/$text/c $newparagraph" $search
It's not working. Is there any way to just add comment symbol not replace the paragraph?
What
I want to the script to do:
search for the paragraph
append
append -- at the end
Edit: This is the paragraph that am trying manipulate :
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.properties</param-value>
</context-param>
<listener>
<listenerclass>
org.springframework.web.util.Log4jConfigListener
</listener-class>
</listener>
This paragraph is part of many paragraphs!
I want make it like this:
<!--
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.properties</param-value>
</context-param>
<listener>
<listenerclass>
org.springframework.web.util.Log4jConfigListener
</listener-class>
</listener>
-->
