java.io.IOException：无法运行程序“/usr/bin/sh”：java.io.IOException：error=2，没有那个文件或目录

Question

i wanted to perform rename and delete function and the environment is LINUX. This is the code which I'm using,

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

But Im getting the following error message,

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

Can anybody help me. Thank-You

Answer 1

As the exception says, there's no file /usr/bin/sh on your system. If you're looking for the Bourne shell, that's /bin/sh .
