    You can do what you want using Archive::Tar so long as IO::Zlib is also installed. The Archive::Tar documentation explains this.

    You could also use 'tar' and 'gzip' commands from the command line - or from within system() commands within perl.

    Cheers,
    Rob
      The second solution looks promising, some time back I was to do the same, here it goes
      $cmd="tar -cvf xyz.tar xyz.txt 2>&1"; system($cmd);
      This creates a archive named xyz.tar containing xyz.txt then
      $cmd="gzip xyz.tar 2>&1"; system($cmd);
      will create the xyz.tar.gz file for you!!

      The world is so big for any individual to conquer

        If your tar supports it, the you can make tar directly invoke gzip in one command, creating a .tar.gz file in one go, using the -z command line switch.
        ... or even (from memory, which at my time of life ain't what it used to be) ...

        `tar -cv xyz.txt | gzip -c > xyz.tgz`;
        At last, a user level that best describes my experience :-))

[1nickt]: I had an interview couople of weeks ago, heard from a principal engineer that a friend of his who works at The Google told him that the self-teaching software that determines the dynamic pricing for their adverts...
[1nickt]: ... has become so complex that there is no one at the Goole who knows what it does.
[marto]: William Gibson was right
[moritz]: a classical problem with machine learning
[1nickt]: moritz isn;t the difference today that the machine learning algos are in charge of most stuffs?
[moritz]: depends on what you mean by "most stuff"
[1nickt]: I am sure I don't know about most of the stuff that is no longer controlled by humans. I do know that it's past the point of determining consumer pricing and into things that can kill me with blunt force!
[holli]: but is this really a problem 1nickt? Nobody knows how your human taxi drivers brain works either
