Kekanap, Have you soved it?
what i didn't got it, is where are you searching for the paterns ? on another file or on several other files ? grep output will be different !

if you are searching for exact same lines in two different files (as the pattern you get from the full line from file1) it might be much easier to just merge the 2 files and look for duplicated lines. that's 1 liner code.

Code:
cat file1.txt file2.txt | sort | uniq -c | grep " 2 "

please let us know if you solved it!

BTW one last comment. I'm not very confident to use grep with patterns that will have "." in it.

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.
