Conventions Used in This Tutorial - BIND DNS Server

Conventions Used in this tutorial

We use the following font and format conventions for Unix commands, utilities, and system calls:

Excerpts from scripts or configuration files are shown in a constant-width font:
```
if test -x /usr/sbin/named -a -f /etc/named.con then /usr/sbin/named fi
```

Sample interactive sessions, showing command-line input and corresponding output, are shown in a constant-width font, with user-supplied input in bold:
```
% cat /var/run/named.pid 78
```

If the command must be typed by the superuser (root), we use the sharp or pound sign (#):
```
# /usr/sbin/named
```

Replaceable items in code are printed in constant-width italics.
Domain names, filenames, functions, commands, Unix manpages, and developing elements taken from the code snippets are printed in italics when they appear within a paragraph.
