Top Forums Shell Programming and Scripting Perl - use search keywords from array and search a file and print 3rd field when matched Post 302743707 by guruprasadpr on Thursday 13th of December 2012 06:47:58 AM

Hi
You should use it like this:

Code:
my ($req_user_info)=grep(/$x/,@input);

This is because grep returns a list, and when used in scalar context, you get the length.

Guru.

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.
