I am using cygwin in my windows machine. I am trying to do a find and it is giving parameter format not correct. Why is that?

```
$ ls
bootstrap.jar
catalina-tasks.xml
catalina.bat
catalina.sh
commons-daemon-native.tar.gz
commons-daemon.jar
cpappend.bat
digest.bat
digest.sh
setclasspath.bat
setclasspath.sh
shutdown.bat
shutdown.sh
startup.bat
startup.sh
tomcat-juli.jar
tomcat-native.tar.gz
tool-wrapper.bat
tool-wrapper.sh
version.bat
version.sh

$ find . -name "version.sh"
FIND: Parameter format not correct

```

* Should I install anything while installing cygwin or am I doing something wrong?
