Join a line to a previous line after finding pattern

[trub1]

I got the script working and the join works I want to also print the lines not matching. The end result would be printing all lines while joining only lines that start with a specific pattern (41 spaces in this case). My script only prints the joins at this point

Here is the script

{if ($0~/ /)print pl,$0;pl=$0}

I am using awk to run myprob.awk which contains the above script

Try this:

{if ($0~/                                         /)print pl,$0;pl=$0;next}
{print}

The latest suggestion gave undesired results.
This is what I am trying to do. My first script does the join but I lose the lines in the output that do not need to be joined. I want to end up with both.

Note you will need to cut the examples into something that doesn't wrap to see the result.

Sorry for the typo. Try this:

$0~/                                         /{print pl,$0;pl=$0;next}
{print}

I am not sure what happened in the newest script change. It looks like it appends the pattern to the next occurance of the pattern. Don't get me wrong I really appreciate any help I can get. Maybe I did not explain what I am trying to accomplish very well

Can you post the input and output files with line numbering
so we can understand what you want to do ?

Maybe

{
if ($0 !~ /^ / && NR>1) print ""
printf $0
}
END{print ""}
