| Run |
Start
menu lists many common Windows XP
applications and accessories, plus any
third-party applications you've installed. It is far
from complete, though, and navigating to the program you want is
often fairly tedious.Ironically, the increasing complexity of the system pushes even the
most graphically oriented user back in the direction of the command
line. Just about the quickest way to run any program that
isn't already on your Desktop is to type the name of
the program at the command line. Windows XP offers three different
command lines: the
Address Bar, the
Run dialog, and the "Address Bar", earlier in this chapter),
it is by far the most convenient of the three command lines. The Run
Dialog is a close second. However, if you are a heavy user of
command-line utilities, you may still find a
command prompt window most useful. The
command prompt window has an advantage in that it provides useful
file management commands such as
dir, del,
copy, and so on.For the most part, though, you can use the three command lines
interchangeably. If you type the name of a Windows GUI application,
it will launch in its own window. If you type the name of a
text-based program (for example, ping) it will
display its output in the current command prompt window, or, if
issued from the Address Bar or Run dialog, will launch its own
command prompt window, which will last only as long as the command
itself executes.
Notes
- You'll only be able to launch a program using the
Run command if that program's
.exe file is in a folder listed in the system
path. See Chapter 6 for details. - One important difference between the one-line prompts (Address or
Run) and a command prompt window is the context in which commands
run. A command interpreter, or
shell, always has a particular
context, or environment, in which it runs. This environment can
create significant differences in the results when you type a command
name. - There are a number of commands you can issue only at a command prompt
window (documented in Chapter 6), all of which
are unavailable from the Run prompt or Address Bar.
