Batch Files
When it comes to quick and dirty scripting, it??™s hard to beat DOS batch
files. Batch files, similar to WSH scripts (discussed earlier in this chapter),
are plain-text files with the .bat or .cmd filename extension. However, rather
than relying on a complex, unfamiliar scripting language, batch files simply
consist of one or more DOS commands, typed one after another.
One of the problems with Windows-based scripting is that it tries to control
a graphical environment with a command-based language. Because DOS is a
command-based interface, DOS-based scripting (batch files) is a natural
extension of the environment.
Consider the following four DOS commands:
c:
cd \windows\temp
attrib -r *.tmp
del *.tmp
If you type these commands into a plain-text editor, such as Notepad, save
them into a .bat file, and then execute the batch file by double-clicking or
typing its name at the Command Prompt, it will have the same effect as if the
commands were manually typed consecutively at the prompt. Obviously, this
Using Long Filenames in the Command Prompt
Given the nature of long filenames (they can have spaces), there are times that
typing them on the command line can cause a problem.
