You might wish to test for a binary file before running dos2unix on it
though or even using sed to substitute ^M$ to remove them.  Binary data
could contain a CRLF that would destroy the binary file if CR is removed.

Also consider doing the same instruction regardless of the OS because
you never know when your script meets a file from a different OS. In the
business world many people send files from Windows to *NIX and vice
versa.  If a text file from *NIX is sent to a user of Windows be sure
that the file contains the appropriate CRLF or the user will just see
garbage unless they are a DevOPS person who knows how to deal with the
file.  I can't count the number of times I've had to resend a file or
help someone adjust one just because the Windows default for .txt files
is Notepad which uses the CR to advance to the next line of the GUI.
