You are correct in noting that you need to use strings when looking for a string in a binary file. The grep utility is only defined to work on text files. This may not be highly efficient, but it should do what you want. First create the following shell script as a file named $HOME/bin/st_gr_pr:
Code:
#!/bin/ksh
# Usage: st_gr_pr pattern file...
pattern="$1"
shift
for f in "$@"
do      if [ $(strings -a -n ${#pattern} "$f" | grep -ic "$pattern" ) -gt 0 ]
        then    printf "%s\n" "$f"
        fi
done

and make it executable using the command:
Code:
chmod +x $HOME/bin/st_gr_pr

Note that the -i option to the grep command in this script makes searches for alphabetic characters case insensitive. I use ksh, but bash should also work if you want to use it in this script.

Then run the command:
Code:
find . -type f -exec st_gr_pr 'srv6000' {} +

to get a list of all regular files rooted in the current directory that contain srv6000, SRV6000, or any of the other six strings with combinations of uppercase and lowercase s, r, and v in that order. Obviously, replace srv6000 if you want to find files containing a different pattern.
works like a charm, perfect answer thanks mate..

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.
