Thank you very much for your quick response. It does not quite yet what I am looking for.. I need only two lines, for what I just changed "NR%2" like this:

Code:

awk '{if (NR%2) {ORS="";print " "$0} else {ORS="\n";print " "$0}}'
 file

The problem is, that I want to print like this only when it meets a patter, for example:

input:

select <something><something>
update <something><something>
<something><something>
insert into <something><something>

output:

select <something><something>
update <something><something><something><something>
insert into <something><something>

I just cant figure out how to do it.. I dont know if I have to use something like

Code:

/update/{ if (NR%2) ..

or

Code:

if((NR%2) && ($1=="nueva"))

both just doesnt work...

Thanks, this works great, but just print the two lines I want in one, that's perfect but it doesnt print the rest of the file. How to make this work then?
