copied!<p>Since you need to match content without including it in the result (must match <code>name="</code> but it's not part of the desired result) some form of zero-width matching or group capturing is required. This can be done easily with the following tools:</p> <h3>Perl</h3> <p>With Perl you could use the <code>n</code> option to loop line by line and print the content of a capturing group if it matches:</p> <pre><code>perl -ne 'print "$1\n" if /name="(.*?)"/' filename </code></pre> <h3>GNU grep</h3> <p>If you have an improved version of grep, such as GNU grep, you may have the <code>-P</code> option available. This option will enable Perl-like regex, allowing you to use <code>\K</code> which is a shorthand lookbehind. It will reset the match position, so anything before it is zero-width.</p> <pre><code>grep -Po 'name="\K.*?(?=")' filename </code></pre> <p>The <code>o</code> option makes grep print only the matched text, instead of the whole line.</p> <h3>Vim - Text Editor</h3> <p>Another way is to use a text editor directly. With Vim, one of the various ways of accomplishing this would be to delete lines without <code>name=</code> and then extract the content from the resulting lines:</p> <pre><code>:v/name=/d :%s/\v.*name\="([^"]+)".*/\1 </code></pre> <hr> <h3>Standard grep</h3> <p>If you don't have access to these tools, for some reason, something similar could be achieved with standard grep. However, without the look around it will require some cleanup later:</p> <pre><code>grep -o 'name="[^"]*"' filename </code></pre> <hr> <h3>A note about saving results</h3> <p>In all of the commands above the results will be sent to <code>stdout</code>. It's important to remember that you can always save them by piping it to a file by appending:</p> <pre><code>> result </code></pre> <p>to the end of the command.</p>
