Perl, searching multiple files and printing returned line to new file
I am trying to find a way to utilise the full potential of my cpu cores and memory on my windows machine.

Now, I am quite familiar with grep, however, running a Unix based OS is not an option right now.

Unfortunately, the 32 bit grep for windows that I am running, I cannot run multiple instances of it or use the full potential.

Therefore I am trying to create a Perl script using Perl x64 can do the following grep:

Code:
grep -h %search_string% *.txt > retuned_Results.sl

Now, I am having troubles with opening multiple files, one at a time and printing out the line matching the search string.

Any pointers on how I should continue would be greatly appreciated.

Thanks for your assistance.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
