java如何执行终端命令？
发现这很棘手；具有以下代码：
String cmd = "find /home/folder/ -type f";
Runtime run = Runtime.getRuntime() ;
Process pr = run.exec(cmd);
pr.waitFor();
我将 pr.getInputStream() 并在那里获得正确的 find 结果，没问题。但是，如果我想更具体一点并将命令设置为 cmd = "find /home/folder/ -type f -name somefile*";，输入流将为空。
现在，我认为这与交互式 shell 完成的字符串扩展有关（我想在本例中不会使用它）。在这种情况下，* 将没有任何意义，find 将查找真正名为“*”的文件（例如 \*）。因此，我尝试将命令设置为 sh -c "find /home/folder/ -type f -name somefile*"。但它也不起作用......
我错过了什么？
谢谢，
f。

Found this to be tricky; Having the following code:
String cmd = "find /home/folder/ -type f";
Runtime run = Runtime.getRuntime() ;
Process pr = run.exec(cmd);
pr.waitFor();
I'll pr.getInputStream() and have the proper find result there, no problem. However, if I want to be a bit more specific and have my command as cmd = "find /home/folder/ -type f -name somefile*";, the input stream will be empty.
Now, I thought it would be something related to the string expansions done by the interactive shell (which wouldn't be used in this case, I suppose). In this case the * would have no meaning, and find would be looking for files really named "*" (something like \*). So I've tried to have my command as sh -c "find /home/folder/ -type f -name somefile*". But it didn't work either...
What am I missing?
thanks,
f.

使用
find时我总是转义通配符：I always escape the wildcard when using
find:我认为如果您使用 ProcessBuilder 或 Runtime.exec 方法会更好，因为它们不需要 shell 转义并且不通过 shell 运行。
I think it would be better if you use ProcessBuilder or maybe Runtime.exec methods as they don't need shell escaping and don't run through the shell.
