Using regular expression format your text

find pattern in text (this kind of regular expression can be use with text editor like notepad++ or sublime):
to find any pattern you want replace text with pattern  :     ^.*pattern.*$
to find any blank line ^.\n
meaning of each character maybe in next post.
or can use sed command in linux box for search pattern:
sed '/^.*object.*$/d' ./filename.txt : this command will print all line NOT include "object" (without quote) of filename.txt in the terminal. 
or say: sed '/^.*object.*$/d' ./filename.txt >> newformatedtext.txt
