Yeah, yeah, I fill in that many an(prenominal) people think voltaic pile bear downs are in the main things of the past. Sometimes, though, a well-conceived group send is just the thing to automatise the job you want to do.
I am not deviation to cover all the theory and practice of kitty files from the footing up. Any good book on commonwealth (now rear in the Antiquities department of your local library <g>), and many of the trounce on Windows, will have a section on batch files. Simply put, a batch file is a plaintext file with a name ending in .BAT. In its simplest form, it contains a series of commands that could be executed from a command prompt (system prompt). The batch file simply autoexecutes them for you. (In fact, AUTOEXEC.BAT is the best known, and most widely utilise, batch file.) To execute a batch file, face its name at a command prompt, or execute a Windows shortcut that does the same thing.
The simplest idea of how to hold open a batch file is: Figure out how you would type the commands at a DOS prompt, then type them, iodin per line, in a text file â€" and youve written your batch file.




However, there are also more sophisticated batch file structures, using simple programming commands built into the batch structure. This article summarizes the most important of these.

Commandline Arguements {%x}
Variables can be inserted into a batch structure in the form of command line arguements. These are in the form %1, %2, etc. To know the variables, type the desired values after the batch file name when executing it.

DOS Environment Variable name {%nn%}
DOS environment variables also can be used as variables in batch files. For example:
COPY %windir%filename a:
