    <p><strong>F1.txt</strong></p> <pre><code>bob tom harry </code></pre> <p><strong>F2.txt</strong></p> <pre><code>bob a=1 b=2 c=3 bob d=4 e=5 f=6 tom a1=34 b1=32 c1=3443 tom a2=534 b2=732 c2=673443 </code></pre> <p><strong><em>result:</em></strong></p> <p><strong>A1.txt</strong></p> <pre><code>bob a=1 b=2 c=3 bob d=4 e=5 f=6 </code></pre> <p><strong>A2.txt</strong></p> <pre><code>tom a1=34 b1=32 c1=3443 tom a2=534 b2=732 c2=673443 </code></pre> <p>I am new to PERL can you kindly help me out in my problem.Now above I have mentioned 2 files namely F1.txt and F2.txt, my job is to search for any element of F1.txt in F2.txt and print the corresponding line along with the next line. If one element is found then the resultant must be saved in a new file,I have given the example A1.txt, it stores all information about bob and similarly A2.txt it stores all information about Tom. Till now i have tried this code, but it is not working efficiently,</p> <pre><code>use strict; use warnings; my $line1; my $line2; my $fh; my $fh1; my $counter; open $fh, "&lt;", "F1.txt" or die $!; open $fh1, "&lt;", "F2.txt" or die $!; my @b = &lt;$fh&gt;; my @a = &lt;$fh1&gt;; for (@b) { $line1 = $_; for (@a) { $line2 = $_; if ($line1 =~ /^$line2$/) { $counter++; open my $outfile, "&gt;&gt;", "A_${counter}.txt"; print $outfile $line2; close $outfile; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
