DELETING BLANK LINES USING GREP
To delete a blank line using a grep command you can use the next
command :-
grep -v "^ *$" file-y > file-x
where file-y is the input files has blank lines and file-x will
be the output file ( excluding the blank lines ).
if we use ( grep -v "^$" ) only , the blanck line which include
spaces will not be removed.
