>Description:
In Chapter 19.12 (Backup Basics) there is a bad command-line example. The handbooks shows the following:

Example 19-2. Using dump over ssh with RSH set
# RSH=/usr/bin/ssh /sbin/dump -0uan -f targetuser at targetmachine.example.com:/dev/sa0 /usr

This won´t work, because this are two commands which are not separated.
>How-To-Repeat:
fgrep '<userinput>RSH' /usr/doc/en_US.ISO8859-1/books/handbook/disks/chapter.sgml
>Fix:
Insert a control operator between the commands like:

# RSH=/usr/bin/ssh && /sbin/dump -0uan -f targetuser at targetmachine.example.com:/dev/sa0 /usr

OR

List the commands, each on a separate line:

# RSH=/usr/bin/ssh
# /sbin/dump -0uan -f targetuser at targetmachine.example.com:/dev/sa0 /usr
