If grep string is found i need to break off and stop the search [this is why i was using break].

If the desired string is not found I need to grep for the string in the other sub directories.

After the process completes I should display the results of the grep if the desired search string has been found in any of the files or else Display a message that "No records Found"

I hope you can give me an idea as my expertise did not help.
And the template I provided in post #4 in the thread Need Linux equivalent for UNIX did exactly that. It includes tested, working code (although it did make a lot of assumptions about things you left unspecified). Did you try starting with that template? What didn't work when you used that template?

And the command:
find * -prune -type d | sort -r -n
gives you directories in reverse alphabetic name order; not reverse order by modification time (assuming that your directory names start with "fd" as in your previous thread's example).

zegrep

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.
