I need to redo my style sheets for 150 jsp files <br />
&nbsp;<br />
I want to find all the unique classes among my jsp files. &nbsp;<br />
<br />
<br />
find . -name &quot;*.jsp&quot; -print | &nbsp;xargs grep &quot;class=&quot; &nbsp;| wc -l<br />
&nbsp; &nbsp; produces 4000+ results<br />
<br />
My guess is that there are only about 200 unique terms in the quotes after class=&quot;className&quot;.<br />
<br />
For example if this was my results, there are only 3 unique classes.<br />
&nbsp; &nbsp;&lt;td class=&quot;columnValue&quot;&gt;<br />
&nbsp; &nbsp;&lt;td class=&quot;myOtherClass&quot;&gt;<br />
&nbsp; &nbsp;&lt;td class=&quot;aThirdClass&quot;&gt;<br />
&nbsp; &nbsp; &nbsp; &lt;td class=&quot;aThirdClass&quot;&gt;<br />
<br />
How do I build a unix command to only show me the unique class=&quot;className&quot; &nbsp;where className is unique?<br />

Need Unix Command Help finding unique values.

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.

System Programming

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
