    <p>I am using CGI script for my website. And I have problem with opening a dynamically generated file. Here is the code:</p> <pre><code>#!/usr/bin/perl my @output = `/export/es_share/Zhou/./notification_finder.sh range $date $time $range $ulh TestProd1 $actionname`; my $filen = $output[0]; open(my $result, "&lt;", $filen) or die "Can't open $filen - $!"; Do something with the file... </code></pre> <p>Always fails, with the output:</p> <pre><code>Can't open /var/tmp/notification-finder-1375086676-658183725.tmp - No such file or directory at /var/www/cgi-bin/appsupport/logapp_test/perltest.cgi line X. </code></pre> <p>While as this succeeds:</p> <pre><code>#!/usr/bin/perl open(my $result, "&lt;", /var/tmp/notification-finder-1375086676-658183725.tmp) or die "Can't open $filen - $!"; Do something with the file... </code></pre> <p>I have also checked if it was the problem of asynchronous execution of the backticks problem, but from my research on stackoverflow it does not seem to be the issue. I also tried this:</p> <pre><code>#!/usr/bin/perl my @output = `/export/es_share/Zhou/./notification_finder.sh range $date $time $range $ulh TestProd1 $actionname`; sleep(10); my $filen = $output[0]; open(my $result, "&lt;", $filen) or die "Can't open $filen - $!"; Do something with the file... </code></pre> <p>I have found this <a href="https://stackoverflow.com/questions/15798111/issue-with-filepath-name-possible-corrupt-characters">similar issue here</a>, but I don't seem to have the same problem as the asker... Thanks for reading this far.</p>

    1. COPerhaps you can use something like [`File::Temp`](http://search.cpan.org/perldoc?File%3A%3ATemp).

    3. CONo, I'm afraid I've never used that module. I'm not sure you can use it in this context, of passing a temp file name to a system command.

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.
