I am looking for a man page, --help or an info page on a redhat 5 system that gives me a clear example of how to use the chcon command.  I forget the syntax and at work I am on a network that does not permit us checking on the web.

#chcon is used to change the context of any file..

# ls -lZ /var/log/messages

#ls -lZ /var/www/html/index.html

above both files have there different contexts.. but to provide reference and change them we use #chcon

#chcon --reference /var/log/messages /var/www/html/index.html

#ls -lZ /var/www/html/index.html

Now index.html also has the same context as /var/log/messages has because we changed it using above command to restore we use .. #restorecon -R /var/www/html/index.html
