Batch file set a example

By Arpit Asati. In laymen terms, we can simply say that the batch file is a simple text file with. A batch script is a file which contains a sequence of command needs to be executed on windows command prompt, batch script is always referred for executing a series of command over the windows command prompt, in Windows operating system it is known as batch script, whereas in Linux it is known as a shell script.

When we execute the batch script file over the command prompt, all the command get executed one by one by following the sequence written in the batch file. Lets save this batch file as test. Comments are very useful to write a description for the command in a large batch file which contains any number of command and reference of another batch file; it makes the batch file easy to understand and modifiable.

This will run java demo jar file, just navigate to your java maven base directory and run this batch file. One is for parameters which can be passed when the batch file is called and the other is done via the set command.

Batch scripts support the concept of command line arguments wherein arguments can be passed to the batch file when invoked. Following is a screenshot of how this would look in the command prompt when the batch file is executed. Following is the syntax of the set command. In the above code snippet, a variable called message is defined and set with the value of "Hello World". In batch script, it is also possible to define a variable to hold a numeric value.

All of the arithmetic operators work in batch files. This is no different from regularly executing FTP with -s option. Script: Download: FtpLoginSharing. The following batch script executes itself in SQL context. The trick is the GOTO command in the first line of the script. The batch script will then run the OSQL. In fact the file can be opened and executed in Query Analyzer as is, since the batch script in the file looks like a comment to the query language processor. Now we can embed SQL queries into a batch file.

But how can we pass arguments from the batch script into SQL? This can be done using a temporary table. Temporary tables live as long as the connection to the SQL Server. EXE twice? The trick is that OSQL allows to use the -i and -q option at the same time whereas: -q specifies a query string to be executed -i specifies a filename with SQL syntax to be executed Both the query string and the SQL file will be executed using the same Server connection.

Some testing shows that the query string -q will always be executed before the -I SQL file, which allows us to use a query string to set up a temporary table. The trick of renaming the Perl. However the solution I have seen so far needed batch code before and after the Perl script where as the solution presented below only needs some lines of DOS at the top.

The added DOS script is generic and works independent from the name of the file. When running the batch the DOS command interpreter will read the first lines and execute the file itself in Perl context. This example works just as the previews one but will wait 4 seconds before the application finally closes. This is just enough time to inspect the screen output before the window vanishes. The delay can probably be done much easier in Perl, but somebody just starting on Perl might find this still useful.
