0.4. Conventions used in this book
Font and format conventions for Unix commands, utilities, and system
calls are:
-
Excerpts from script or configuration files will be shown in a
constant-width font:
192.9.200.1 bitatron
-
Sample interactive sessions, showing command-line input and
corresponding output, will be shown in a constant-width font, with
user-supplied input in bold:
% ls
foobar
-
If the command can be typed by any user, the percent sign
(%) will be shown as the prompt. If the command
must be executed by the superuser, then the pound sign
(#) will be shown as the prompt:
# /usr/sbin/ypinint -m
-
If a particular command must be typed on a particular machine, the
prompt will include a hostname:
bitatron# mount wahoo:/export /mnt
-
Inside of an excerpt from a script, configuration file, or other
ASCII file, the pound sign will be used to indicate the beginning of
a comment (unless the configuration file requires a different comment
character, such as an asterisk (*)):
#
#Hal's machine
192.9.200.1 bitatron
-
Unix commands and command lines are printed in italics when they
appear in the body of a paragraph. For example, the
ls command lists files in a directory.
-
Hostnames are printed in italics. For example, server
wahoo contains home directories.
-
Filenames are printed in italics, for example, the
/etc/passwd file.
-
NIS map names and mount options are printed in italics. The
passwd map is used with the
/etc/passwd file, and the
timeo mount option changes NFS client behavior.
-
System and library calls are printed in italics, with parentheses to
indicate that they are C routines. For example, the
gethostent( ) library call locates a hostname in
an NIS map.
-
Control characters will be shown with a CTRL prefix, for example, CTRL-Z.
