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. -- cyg Simple -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
