You want to find a repeating string in a single line

pattern='whatever I want to find goes here'
awk -v patt="$pattern" '  {i=index($0, patt ) 
                                   if(i && index(substr($0, i+1), patt ) )> 0 
                                        {print "found: ", $0} 
               } ' inputfilename

sed 's/Srinivas Jala/Found/1' file
