cdef |\N|\N|\N| end
Please send me email directly!! Thanks!!

s/123 | 456 || abc ||| cdef |||| end/123 | 456 |\N| abc |\N|\N|cdef
|\N|\N|\N| end/
(in one line, of course)
This does do what you asked for but maybe meant to ask for something
different?

Please send me email directly!! Thanks!!

That's not how Usenet works.

No idea what you mean with "Reply All". How do you post a reply on Usenet
that is not visible to all?

Sorry for the wording 'Please send me email directly'

Actually this is what I am doing,

cat some_file | sed 's/|||/|\\N|\\N|g' | sed 's/||/|\\N|/g'

and I do not know the occurence of ||, |||, ||||, |||||, ....
All I want to do is to convert

|| to |\N|
||| to |\N|\N|
|||| to |\N|\N|\N|
|||| to |\N|\N|\N|\N
.....

Thanks in advance.

It's not the wording that is objectionable, it is the sentiment.

cat some_file | sed 's/|||/|\\N|\\N|g' | sed 's/||/|\\N|/g'

Well, since this is a Perl news group, the obvious answer is use Perl
(probably with the -p and -e swiches) not sed. (Correct Perl command
has already been given).

Since this is not a Unix newsgroup I woln't mention that you have a
useless use of cat.

Reply All means to reply to everyone on the From, Cc, and Reply-to
lists. By doing so you will send the message to the newsgroup and to the
person who originated the message. Most newsgroup readers have a method
to do this with one click of the mouse or if text based, with a single
command. Check the help for your reader.
