The web server account is the same as the one who creates temporary directory in Solaris command line directly. It is weird that the same programme works by running 'perl test.pl',however, when the same code section is invoked in a web-based procedure, I can't find the temporary directory by 'ls -l /tmp/temp_dir_created_by_File_Temp'. 
#!/usr/bin/perl
use strict;
use warnings;

use File::Temp qw/ tempfile tempdir /;

my $temp_dir       = tempdir();
$temp_dir =~ /\/tmp\/(.*)/;
my $temp_dir_name = $1;

my $grep_str = "ls -l /tmp | grep $1";
my $res2 = `$grep_str`;
print "[$grep_str]grep result [$res2]\n";
