Hi,
Follow this link for all you vi queries.
http://www.vmunix.com/~gabor/vi.html

For this query use
Eec
:g/^[ ^I]*$/d
First check this in a test file

Hi Shaikh ,

Bye.

If the lines are really empty (no spaces or tabs):
:g/^$/d

Otherwises:
:g/^[ X]*$/d
where X is a TAB character which is difficult to type in the forum.

You may want to use sed i.s.o. of vi.

And to add an alternative:

# perl -pi -e's/^\s*$/ and$_=""' file

will delete all lines in file "file" that have only blanks

Enjoy, Have FUN! H.Merijn

Somewhat esoteric commands, but here is a really simple method:

rmnl | ssp >

cat filename |grep -v "^$" > newfile
