Unusual batch commands

Anyone can use batch commands such as DEL or XCOPY and add a few more fixed parameters and paths. But there are also some rather special batch commands, but which can greatly help you.

Batch commandexample callusage example
%CD%MOVE * .docx &# 8220;%CD%/ DOCS /The% CD% of the entire current path is replaced. In the left-standing call so all files will be moved with the extension .docx to a subdirectory of the current path. Commands such as MOVE need to perform the complete path that you do not have to enter in this way. So with such a command you can clean up directories and move data effectively.
% 1,% 2,% 3 ...Batch line:
echo So you say %1


Batch call:
Name.BAT Erwin

So you called Erwin

Batch commands can process multiple variables. You call the batch file and inserts manually the contents of the variable back to the command an.Die command line batch.bat Huhu Hello Tach So passes the three variables Huhu, Hello and tach to the batch commands in the batch file. Your order specifies the same also determine the number of the variable. Since Hi is in second place, it would used where is filed in batch file% 2. Huhu is therefore% 1 and Tach% 3. If in the batch file only one variable is used, in addition passed variables are ignored.
> (Greater than sign)TO YOU *.* > liste.txtDIR *. * > NUL
(NUL output suppressed in this case completely)
The greater than sign > is a redirector for batch commands. Instead ie at about DIR *. * To list all files in Windows, this character ensures that the output of the command is redirected to a file. Which then provides a list of all files and their attributes.
CHOICEchoice / M &# 8220; Do you want a listing, Yes or No&# 8221;
IF ERRORLEVEL 1 GOTO label1: Make2
EXIT: Brand1
to you *.*
CHOICE prompts the user for a decision. This can be preset and contain letters or numbers bestehen.Die ERRORLEVEL are processed from back to front. The first answer (as Yes) returns 1 ERRORLEVEL, the second selection yields ERRORLEVEL 2 usw.Ihr then can jump to jump labels, behind which follow commands.

CHOICE /? Explains the batch command.

batch command-choiceCHOICE allows you to choose which batch commands are then executed

Characteristics of the batch commands

Batch commands are executed one after another. This not only means that they are executed in a predetermined order. This means in particular that the subsequent instruction waits until the previous is finished! So you will not start as with a batch command five applications at once, but five programs consecutively.

Batch commands can be called with parameters in turn. So if you are not just clicking a batch file, but manually calling on the command line, then you can still attach behind a few other parameters. A small example:

If a program creates its own temporary folder on any media, and it does not clean, then you could write to correct a batch file. The file weg.bat then contains, for example, the line


But if it is always such a folder on D: and E are, then would have to be specially considered. So you wear either for each of these drives another line, or you use a variable as a placeholder. These variables can enumerate her and the first is, therefore,% 1. Puts them where something changes. So in my example the drive letter. The line is then


And is called the weg.bat with the attached variable. The call weg.bat C deletes the folder on drive C :. And starts her weg.bat e, then the folder is on E: deleted.

Important: It is just that taken in the variable, which is afterwards added manually. Without this input variable batch commands do not work. And you had as a batch command equal del% 1 taken, so you would have the whole path manually attached to the batch file.

always reach batch commands

Usually your batch files are not necessarily where they are needed. So you need to either get copied, where they are needed, or specify as variables endless paths. But finally there is the system environment variables on Windows.
