这是我的dos命令代码。
我需要将当前文件名从我的重命名批处理工具中提取dos command到运行中。很确定我只是打破命令
add +filename+ with quotes like "cmd /c \\Converter.exe \\android\\"+filename+" -android -o \\android\\"+filename
但是我的文件在另一个class. eclipse 建议getfilename(null)不起作用。
我怎样才能做到这一点？下面我尝试了通配符，这当然不起作用。
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class doscommand {
public static void run() {
try {
Runtime rt = Runtime.getRuntime();
//Process pr = rt.exec("cmd /c dir");
Process pr = rt.exec("cmd /c \\Converter.exe \\android\\*.sdtid -android -o \\android\\*.txt");
BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line=null;
while((line=input.readLine()) != null) {
System.out.println(line);
}
int exitVal = pr.waitFor();
System.out.println("Exited with error code "+exitVal);
} catch(Exception e) {
System.out.println(e.toString());
e.printStackTrace();
}
}
}
