Combining two text lines into one
Here is the sample file:
646 STARTED Tue Dec 30 06:38:53 2008
Job DdCustXAddr_brad has been reset.
647 STARTED Tue Dec 30 06:38:54 2008
Starting Job DdCustXAddr_brad. (...)
704 STARTED Tue Dec 30 06:49:02 2008
Job DdCustXAddr_brad aborted.


I want to combine every non-numbered line with the previous line.

and end up with:
646 STARTED Tue Dec 30 06:38:53 2008 Job DdCustXAddr_brad has been reset.
647 STARTED Tue Dec 30 06:38:54 2008 Starting Job DdCustXAddr_brad. (...)
704 STARTED Tue Dec 30 06:49:02 2008 Job DdCustXAddr_brad aborted.

Hammer & Screwdriver here is one approach to ponder...
Code:
> cat file17
Here is the sample file:
646 STARTED Tue Dec 30 06:38:53 2008
Job DdCustXAddr_brad has been reset.
647 STARTED Tue Dec 30 06:38:54 2008
Starting Job DdCustXAddr_brad. (...)
704 STARTED Tue Dec 30 06:49:02 2008
Job DdCustXAddr_brad aborted.

> cat file17 | sed 's/^[0-9]\{3\}/~&/' | tr "\n" " " | tr "~" "\n"
Here is the sample file: 
646 STARTED Tue Dec 30 06:38:53 2008 Job DdCustXAddr_brad has been reset. 
647 STARTED Tue Dec 30 06:38:54 2008 Starting Job DdCustXAddr_brad. (...) 
704 STARTED Tue Dec 30 06:49:02 2008 Job DdCustXAddr_brad aborted.
