How do I exclude a file from batch execution?

I wrote a batch file that compiles all .java files using javac:

javac *.java

But then I added another file, which I do not want to compile. For example let's name it ignored.java

Is there a way in batch programming to exclude something from code execution?

Something like:

javac *.java /except ignored.java

cmd requires a for loop to do something for each item. if can be used to compare. That will give you a solution of:

@echo off
for %%i in (*.java) do if /i not "%%~i" == "ignored.java" javac "%%~i"

Note also the /i switch for if which makes the comparison case insensitive.

Another way is to use Argument File

Create a file named classes that contains only files to be compiled like following:

MyClass1.java
MyClass2.java
MyClass3.java

You can do that like this:

dir *.java /a:-d /b|find /i /v "ignored.java">classes

Then, run the javac command as follows:

javac @classes

As ignored.java is not mentioned in classes file, it will be skipped
