12 Preface About This Book
Parameters You Must Type as Shown
If you need to type a parameter as shown, it appears following the command in the
same font. For example,
$ doit -w later -t 12:30
To use the command in the above example, type the entire line as shown.
Parameter Values You Provide
If you need to supply a value, its placeholder is underlined and has a name that
indicates what you need to provide. For example,
$ doit -w later -t hh:mm
In the above example, you need to replace hh with the hour and mm with the minute, as
shown in the previous example.
Optional Parameters
If a parameter is available but not required, it appears in square brackets. For example,
$ doit [-w later]
To use the command in the above example, type either doit or doit -w later. The
result might vary but the command will be performed either way.
Alternative Parameters
If you need to type one of a number of parameters, they’re separated by a vertical line
and grouped within parentheses ( | ). For example,
$ doit -w (now|later)
To perform the command, you must type either doit -w now or doit -w later.
Default Settings
Descriptions of server settings usually include the default value for each setting. When
this default value depends on other choices you’ve made (such as the name or IP
address of your server, for example), it’s enclosed in angle brackets .
For example, the default value for the IMAP mail server is the host name of your server.
This is indicated by mail:imap:servername = "".
