Are you sure you mean an extra newline at the end of the file, as in, two? Or just one newline at the end of the file? One newline at the end of the file may look like an extra blank line but is really just one character. Many text editors won't even create a text file without at least one newline at the end of file.

Even gcc gives a warning about no newline at the end of the file(Not an error mind you, just a warning), it may be traditional/standard behavior. On one hand it's a stupid thing to be picky about, on the other hand it's a silly thing to quibble about either -- not hard to add one newline to one file once and be done with it.

cr

cr(1)							      General Commands Manual							     cr(1)

NAME

       cr - converts text files between nix EOL and dos EOL

SYNOPSIS

       cr  - | +  <input file> <output file>

DESCRIPTION

       Text  files,  such  as tle files, that come from a dos source usualy have the ^M symbol at the end of every line. Cr converts files between
       the dos newline format and the normal *nix newline format by stripping the ^M to convert dos to *nix, using the '-' option, or adding ^M to
       a *nix file to create the proper dos file when the '+' option is used.

       Although this extra character is not often a problem, programs like seesat5, which are data driven will encounter parsing problems when the
       extra character is present. It is these problems that cr is intended to repair.

   Options
       - | +  One or the other of these options is required. The '-' option is used to remove ^M from all newlines found in the dos file. The  '+'
	      option is used to add ^M to every newline found in a *nix file.

       input file
	      Fully delineated path to the input file. As this program is used in the dos environment as well, standard input is not used.

       output file
	      Fully delineated path to the output file. As this program is used in the dos environment as well, standart output is not used.

BUGS

       Cr  is  not an inteligent program. It methodicaly replaces/removes the offending character when it finds it in the correct context. Newline
       sequences found in contexts other than 'newline' will be replaced/removed just like those found in the proper  context.	Passing  a  binary
       file through cr is not advised, for this reason. Send all inqueries to Dale Scheetz <dwarf@polaris.net>.
