java.io.IOException：無法運行程序“/usr/bin/sh”：java.io.IOException：error=2，沒有那個文件或目錄

Question

我想執行重命名和刪除功能，環境是LINUX。 這是我正在使用的代碼，

String[] command_ary = { "/usr/bin/sh", "-c", command };
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec( command_ary );

但我收到以下錯誤消息，

java.io.IOException: Cannot run program "/usr/bin/sh": java.io.IOException: error=2, No such file or directory

有誰能夠幫我。 謝謝

Answer 1

正如例外所說，您的系統上沒有文件/usr/bin/sh 。 如果您正在尋找 Bourne shell，那就是/bin/sh 。
