>Description:
The FreeBSD's version of "cat" is able to display directory contains:

$ cat /etc
(garbage)

Solaris (tested with SunOS 5.9) shows the same behavior.

The behavior on directories in not described in the manual page. 

>How-To-Repeat:
$ cat /etc
>Fix:
"cat" from "coreutils" (GNU Linux) refuses to display directory contents.

$ cat /etc
cat: /etc: Is a directory
