Typographic Conventions
ix
File-related classes include
filesystem
for file systems,
file
for files, and
dir
for
directories. Each class has its own associated set of permissions.
Proportional Bold
This denotes words or phrases encountered on a system, including application names; dialogue
box text; labelled buttons; check-box and radio button labels; menu titles and sub-menu titles. For
example:
Choose
System > Preferences > Mouse
from the main menu bar to launch
Mouse
Preferences
. In the
Buttons
tab, click the
Left-handed mouse
check box and click
Close
to switch the primary mouse button from the left to the right (making the mouse
suitable for use in the left hand).
To insert a special character into a
gedit
file, choose
Applications > Accessories
> Character Map
from the main menu bar. Next, choose
Search > Find…
from the
Character Map
menu bar, type the name of the character in the
Search
field and click
Next
. The character you sought will be highlighted in the
Character Table
. Double-
click this highlighted character to place it in the
Text to copy
field and then click the
Copy
button. Now switch back to your document and choose
Edit > Paste
from the
gedit
menu bar.
The above text includes application names; system-wide menu names and items; application-specific
menu names; and buttons and text found within a GUI interface, all presented in Proportional Bold and
all distinguishable by context.
Note the
>
shorthand used to indicate traversal through a menu and its sub-menus. This is to avoid
the difficult-to-follow 'Select
Mouse
from the
Preferences
sub-menu in the
System
menu of the main
menu bar' approach.
Mono-spaced Bold Italic
or
Proportional Bold Italic
Whether Mono-spaced Bold or Proportional Bold, the addition of Italics indicates replaceable or
variable text. Italics denotes text you do not input literally or displayed text that changes depending on
circumstance. For example:
To connect to a remote machine using ssh, type
ssh username @ domain.name
at
a shell prompt. If the remote machine is
example.com
and your username on that
machine is john, type
ssh john@example.com
.
The
mount -o remount file-system
command remounts the named file
system. For example, to remount the
/home
file system, the command is
mount -o
remount /home
.
To see the version of a currently installed package, use the
rpm -q package
command. It will return a result as follows:
package-version-release
.
Note the words in bold italics above — username, domain.name, file-system, package, version and
release. Each word is a placeholder, either for text you enter when issuing a command or for text
displayed by the system.
Aside from standard usage for presenting the title of a work, italics denotes the first use of a new and
important term. For example:
When the Apache HTTP Server accepts requests, it dispatches child processes
or threads to handle them. This group of child processes or threads is known as
