I have placed the text file "FilenameKeyword.txt" file in E:/Test folder, in my perl script i am trying to traverse through the folder and am i am trying to find a file with filename which has the string "Keyword" in it, later i have printed the content of that file in my script. Now i wish do the same thing for the file which is placed inside tar file which is compressed.
Hypothetical File from where i am trying to extract the details: E:\test.tar.gz
Wanted to know if there are possibility in perl to search and read the file without decompressing /unzipping the hypothetical file.If that is not possible, I shall also allocate some temperory memory to decompress the file , which should deleted after extracting the content from the particular text file.
While Searching in the internet i could it is possible to extract and read the gzip/tar file by using Archive::Extract, being new to Perl - i am really confused on how actually i should make use of it. Could you please help on this....
Input file:FilenameKeyword.txt
Script:
use warnings;
use strict;
my @dirs = ("E:\\Test\\");
my %seen;
while (my $pwd = shift @dirs) {
opendir(DIR,"$pwd") or die "Cannot open $pwd\n";
my @files = readdir(DIR);
closedir(DIR);
foreach my $file (@files)
{
if (-d $file and ($file !~ /^\.\.?$/) and !$seen{$file})
{
$seen{$file} = 1;
push @dirs, "$pwd/$file";
}
next if ($file !~ /Keyword/i);
my $mtime = (stat("$pwd/$file"))[9];
print "$pwd$file";
print "\n";
open (MYFILE, "$pwd$file");
while (my $line = <MYFILE>){
#print $line;
my ($date) = split(/,/,$line,2);
if ($line =~ s!<messageText>(.+?)</messageText>!!is){
print "$1";
}
}
}
}

I was stuck in using CPAN module, CPAN module didn't work for me as i have oracle 10g enterprise edition in the same machine, due do some software conflict Active state perl was unable compile and refer to the perl lib for CPAN module, i have uninstalled oracle in my machine to make this work....
#!/usr/local/bin/perl
use Archive::Tar;
my $tar = Archive::Tar->new;
$tar->read("test.tar.gz");
$tar->extract();
