More detail definitely needed. When you say insert into another text file, do 
you mean you want to create an output file in which each line is identical 
bar the four parameters from the first file (in other words your bla bla bla 
is the same for every input line) (in which case a simple awk '{printf}' will 
meet the need), or are you actually doing a merge of two files where bla bla 
bla represents the text from the next line of the other input file and 
changes from line to line?
