convert text file line endings between Windows CR/LF and Linux/Mac OS X format with a free open source command line tool for Windows, Mac OS X, Linux and Raspberry Pi.
command line examples with sfk:

sfk remcr mybatch

converts the single file mybatch

sfk remcr . .txt

converts all .txt files in the current directory
AND in all subdirectories.

sfk remcr -dir FooBank -file .hpp

converts all .hpp files in the directory tree FooBank.

sfk addcr -dir . -file .txt -norec

changes LF endings into CR/LF for Windows,
on all .txt files of the current directory,
but NOT within subdirectories (no recursion).
to find out if a file contains LF or CRLF line endings, you may use the command:
sfk hexdump -showle testfile.txt

example output:

testfile.txt :

   in this example, we see that the file contains CR/LF line endings (or 0x0D0A),
   i.e. it has DOS/windows format. to convert it into a linux-compliant format,
   we run the command
sfk remcr testfile.txt
   afterwards, the same hexdump command produces this:
testfile.txt :
