What is the best way to gunzip files with Perl?
Is there a faster solution than my actual 'zcat' solution to gunzip files with Perl? A little benchmark: #!/usr/bin/perl use strict; use warnings; use Benchmark qw(cmpthese timethese); use IO::Uncompress::Gunzip qw(gunzip); my $re = qr/test/; my $bench = timethese($ARGV[1], { zcat => sub { if (defined open(my $FILE, "-|", "zc...
Unzipping unfinished gzip...possible?
So I just spent a week running a simulation, but the computer had to be turned off to move it (terrible, I know). The data that was being produced was being zipped due to it's size by piping it into gzip, but since the simulation wasn't finished, I can't unzip the .gz file. We have since started the simulation over, but I was wondering...

Hi. I'm on a shared server with restricted disk space and i've got a gz file that super expands into a HUGE file, more than what i've got.

uzing libgz to inflate a gz input
Hi all, I'm currently trying to use the zlib to inflate a source of gzipped data. It seems that the inflate API in zlib cannot inflate a gzipped data ( The example http://www.zlib.net/zpipe.c fails to read a gzipped file: "zpipe: invalid or incomplete deflate data" ). I noticed that there is a gzopen function in this API, but , as far a...
Why is my programmatic compression dropping the file extension?
I am using C# to programatically compress an xml file. Compression works fine, but when I gunzip the file from the command line, the extension has been dropped. Why would this be? The destination file coming in has the gz extension while the source file has an xml extension. Here is my compression code: using (FileStream...
