Hello,

the smbclient(1) has a missing space:
"One useful trick is to cat the message throughsmbclient."

Its the same problem as described in #3146

                <para>One useful trick is to cat the message through
                <command>smbclient</command>. For example: <command>
                cat mymessage.txt | smbclient -M FRED </command> will
                send the message in the file <filename>mymessage.txt</filename>
                to the machine FRED. </para>

Just move the first <command> to the first line should fix this problem.

Thank you.
