Help Needed in SED

Hi All ,

I have a input file which has set of lines like this ::

cat a.txt

unix1 djkdfkjdkkdfkdjfdfkjd 09191091 unix@unix.com <2008-23-07>
unix 2 dfdfdfdfdfdfdfdfdfd

unix3 dfldfljdflkjdfldfkljdfldjfl 0565606 unix1@unix.com <2008-10-09>
unix4 dfdlfndfldflnlffddfd

for some reason when i execute the SED command to bring it to single line , the code works partially

sed '=' a.txt | \
sed '{
N
s/\n/ /
}' a.txt > b.txt


the output is like this ::

unix1 djkdfkjdkkdfkdjfdfkjd 09191091 unix@unix.com <2008-23-07> unix 2 dfdfdf
dfdfdfdfdfdfd
unix3 dfldfljdflkjdfldfkljdfldjfl 0565606 unix1@unix.com <2008-10-09>
~

can you help me how to bring all those lines into single lines my output should be something like this :::


unix1 and unix2 shoule be in a single line
unix1 djkdfkjdkkdfkdjfdfkjd 09191091 unix@unix.com <2008-23-07> unix 2 dfdfdfdfdfdfdfdfdfd

and unix3 and unix4 should be in single line :::


unix3 dfldfljdflkjdfldfkljdfldjfl 0565606 unix1@unix.com <2008-10-09> unix4 dfdlfndfldflnlffddfd

NAME
Jifty::Plugin::User::Mixin::Model::User - user model base mixin SYNOPSIS
package MyApp::Model::User; use Jifty::DBI::Schema; use MyApp::Record schema { # column definitions }; # Import columns: name, email and email_confirmed use Jifty::Plugin::User::Mixin::Model::User; DESCRIPTION
This mixin may be added to a model to give your user accounts a name and an email address. This module may be used as the basic building block for building account models in your application. It can be combined with mixins from an authentication plugin to create an object suitable for a given authentication mechanism. SCHEMA
This mixin model adds the following columns to the model. name This is the username/nickname for the user of the account. email This is the email address of the account. It is intended as a bare minimum confirmation of identity and for communication of password resets and other account information. email_confirmed This is a flag indicating whether the user has confirmed ownership of the given email address. METHODS
set_email ADDRESS Whenever a user's email is set to a new value, we need to make sure they reconfirm it. validate_email Makes sure that the email address looks like an email address and is not taken. SEE ALSO
