批处理文件 - 检查参数 [英] Batch files - checking arguments
问题描述
我要创建三个批处理文件。其中2是配置环境变量，另将运行一个例子。
然后，我有confvarsC.bat（C + +环境变量）和confvarsJ.bat（Java环境变量）。
然后，我创建了执行以下操作的executePortico.bat：测试JAVA_HOME的rti_home并调用环境变量的文件。
但我需要，如果人键入C应该叫confvarsC.bat和运行C的例子+ +，如果人型J应该叫confvarsJ.bat和运行Java的例子。
看到我所做的：

在：checkargs ，％0 将永远在东西 - 即批处理文件的名称 - 因此没有必要测试值
％1 是第一个参数，所以：rtihometest 你需要比较的％1 C或Ĵ，不是％0
在：execC ，你没有任何地方的第二次测试后跳，所以：execJ 也将被执行

I had to create three batch files. two would be to configure the environment variables and the other would run an example.
Then I have confvarsC.bat (C + + environment variables)and confvarsJ.bat (Java environment variables). And then I created the executePortico.bat that does the following: tests the java_home the rti_home and calls the file of environment variables. But I need that if the person typing "c" should call the confvarsC.bat and run the examples in C + +, if the person type "j" should call the confvarsJ.bat and run the Java examples.
See that i did:

I did this, see my code please: But i have a problem, when I try to run a Java example, he does not enter the executeJava, he always goes into executeC.

in your :checkargs, %0 will always have something in - that is the name of the batch file - so there is no need to test that value
%1 is the first parameter, so in :rtihometest you need to compare %1 with c or j, not %0
in :execC, you do not jump anywhere after the second test, so :execJ will be executed too.
in :execJ, you do not jump anywhere after the second test, so :execute will be executed regardless of the result of the test.
