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..

binfmt.d

BINFMT.D(5)							     binfmt.d							       BINFMT.D(5)

NAME

       binfmt.d - Configure additional binary formats for executables at boot

SYNOPSIS

       /etc/binfmt.d/*.conf

       /run/binfmt.d/*.conf

       /usr/lib/binfmt.d/*.conf

DESCRIPTION

       At boot, systemd-binfmt.service(8) reads configuration files from the above directories to register in the kernel additional binary formats
       for executables.

CONFIGURATION FORMAT

       Each file contains a list of binfmt_misc kernel binary format rules. Consult binfmt_misc.txt[1] for more information on registration of
       additional binary formats and how to write rules.

       Empty lines and lines beginning with ; and # are ignored. Note that this means you may not use ; and # as delimiter in binary format rules.

       Each configuration file shall be named in the style of program.conf. Files in /etc/ override files with the same name in /usr/lib/ and
       /run/. Files in /run/ override files with the same name in /usr/lib/. Packages should install their configuration files in /usr/lib/, files
       in /etc/ are reserved for the local administrator, who may use this logic to override the configuration files installed from vendor
       packages. All files are sorted by their filename in lexicographic order, regardless of which of the directories they reside in. If multiple
       files specify the same binary type name, the entry in the file with the lexicographically latest name will be applied.

       If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null
       in /etc/binfmt.d/ bearing the same filename.

EXAMPLE

       Example 1. /etc/binfmt.d/wine.conf example:

	   # Start WINE on Windows executables
	   :DOSWin:M::MZ::/usr/bin/wine:
