Add a Couple of Carriage returns to text file

I have a directory of over a hundred text files that I'm getting ready to merge with the CAT command. However there is only one space after each file; this makes the output look crowded.

I would like to add two, possibly even four carriage returns at the end of each text file to make the final product a bit more readable.

I checked out another thread about this but the solution didn't work for me; I got a "bash: *.txt: ambiguous redirect"

Yes I had a cloudy moment where I didn't get that error message but I ate lunch with my son and came back to the problem and it made a whole lot more sense.

So I then tried a couple of other options where I specified the output but can't quite get the line carriage solution.

Thanks for any help you might give.

P.S. If you are interested in which thread I was looking at, search this forum for "add-carriage-return-end-file". It'll come up as the first post (sorry the system doesn't allow me to post links yet) :-)

Ok never mind ... Hope this helps someone else but I managed to dig around and try many many different variances until one worked. This is what did it for me.

Let me know if you can think of any improvements or anything that I'm overlooking.

Code:

sed -i '$ s/$/ \r\r/' *

asa

ASA(1)							    BSD General Commands Manual 						    ASA(1)

NAME

     asa -- interpret carriage-control characters

SYNOPSIS

     asa [file ...]

DESCRIPTION

     The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to
     the standard output.

     The first character of each line is interpreted as a carriage-control character.  The following characters are interpreted as follows:

     <space>  Output the rest of the line without change.

     0	      Output a <newline> character before printing the rest of the line.

     1	      Output a <formfeed> character before printing the rest of the line.

     +	      The trailing <newline> of the previous line is replaced by a <carriage-return> before printing the rest of the line.

     Lines beginning with characters other than the above are treated as if they begin with <space>.

EXIT STATUS

     The asa utility exit 0 on success, and >0 if an error occurs.

EXAMPLES

     To view a file containing the output of a FORTRAN program:
	   asa file

     To format the output of a FORTRAN program and redirect it to a line-printer:
	   a.out | asa | lpr

SEE ALSO

     f77(1)

STANDARDS

     The asa utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'') and to X/Open Commands and Utilities Issue 5 (``XCU5'').
