Class crlf

public class crlf
extends java.lang.Object
implements java.io.FilenameFilter

How many times have you transferred files from a UNIX machine to Windows or vice versa and then discovered that you did a binary transfer by mistake? What do you do then? You can ftp them again! What about downloaded files? I can give you one example - JDK sources from Sun. They always come with UNIX style line feeds only. Viewing them with notepad becomes a pain. So here's an utility to make life simpler. Just run this utility against your file and bingo! all those black boxes and ^M are gone.

Usage:
java crlf [-template template] [-recurse] file1 file2 ...
template can be a simple wild card with '*' and '?'
recurse option enables resursing sub-directories
filename can be name of a file or a directory
