Question

如何用java调用linux shell命令

Answer 1

代码方法如下：
public static ArrayList<String> command(final String cmdline,
final String directory) {
try {
Process process =
new ProcessBuilder(new String[] {"bash", "-c", cmdline})
.redirectErrorStream(true)
.directory(new File(directory))
.start();

ArrayList<String> output = new ArrayList<String>();
BufferedReader br = new BufferedReader(
new InputStreamReader(process.getInputStream()));
String line = null;
while ( (line = br.readLine()) != null )
output.add(line);

//There should really be a timeout here.
if (0 != process.waitFor())
return null;

return output;

} catch (Exception e) {
// 处理异常
}
}
