If this is the case:

Code:
sed -n 'N;N;s/[^M^Y]//g;s/\n//gp;N;N

This will first read two additional lines (to the first read line) from the file and combine these into the pattern space. The first replacement then throws out the control characters (^M and ^Y, enter them via <CTRL-V> in vi), the second replacement removes the newline characters combining the lines to one line and prints it. Then two additional lines (the separator lines) are read and discarded, since they are not printed at all, then repeat from start.

I hope this helps.

What if the number of lines of the original file is unknown ?

In my example I gave 3 lines but it can be anything between 1 and 20 lines. The file contains any multi-line amount of records. Each records is totally independent from the previous one. One record could have 2 lines, the next 20, the next 5, ... No regular patterns for the amount of lines. The file contains a list of system generated alarms coming from 20 different servers, numerous amount of workstations, ...

Sorry I forgot to mention it.
