抑制控制台错误

Question

我正在写一个bash脚本，显示了我的树莓派Linux操作系统中的最大文件

我怎么能抑制读取错误的目录上 控制台输出类似的lost + found等？

du/-Sh | sort -rh | head -n 15 

输出示例：

du: cannot access `/proc/2884/task/2884/fd/4': No such file or directory 
du: cannot access `/proc/2884/task/2884/fdinfo/4': No such file or directory 
du: cannot access `/proc/2884/fd/4': No such file or directory 
du: cannot access `/proc/2884/fdinfo/4': No such file or directory

可以使用：

du/-Sh 2>/dev/null | sort -rh | head -n 15 

即stderr重定向在du命令空设备。
