Command Conventions

There are some examples of commands scattered through the book, especially in sections and appendices that deal with administration. By convention, most examples are shown as they would be executed on a Unix system, e.g.:

Enter keystore password: ******
Certificate stored in file </tmp/sdo.cer>

In these examples, the text typed by the user or administrator is always shown in bold font; the remaining text is output from the command (the string piccolo% indicates a command prompt). On other systems, the names of the files would have to be changed to conform to that system (e.g., C:\sdo.cer for a Microsoft Windows system). Keep in mind, however, that the command-line arguments often specify a URL rather than a filename, in which case you must use forward slashes. In that case, the argument is often the same, although on Microsoft Windows systems you must specify a drive: the Unix directory file:///files/sdo/ is rendered on Microsoft Windows as file:/C:/files/sdo/. When an argument requires a URL, ...
