通过其他程序或脚本在非交互式模式下调用top命令，经常会出现:
top: failed tty get 错误

解决办法：加个-b 选项皆可

-b : Batch mode operation
Starts top in Batch mode, which could be useful for sending output from top to other programs or to a file. In this mode, top will not accept input and runs until the iterations limit youve set with the -n command-line option or until killed.

例如执行：top -bn 1

这样就可以了：

nohup top -b &
