I'm wondering what I'm missing.

Every hour I receive a bunch of data which I write into a compressed (gzip) text file.

I collect all the 24 data deliveries into one file by simply appending to the file created in the first hour.

When I do a gunzip -c myfile.gz I can see all my data.

Whenn I open the same file with PerlIO::gzip I only get the first set of data.

Here is a small script to reproduce:

use PerlIO::gzip;
open my $out, ">:gzip", "tst.gz";
print $out "111111111111111111111111\n" x 100;
close $out;
open my $out, ">>:gzip", "tst.gz";
print $out "222222222222222222222222\n" x 100;
close $out;

open my $in, "<:gzip", "tst.gz";
print while <$in>;
close $in;

Question is: How can I convince perl to continue reading data?

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e
