If there is a need to output to a log file to go, and then use more / less command to view
If you are switching to running in the background, using the Ctrl+z
then fg command tail command to the foreground to continue viewing.

[1]+ Stopped top
[2]- ./xxxxx( Stopped tar-zcf etc.tar.gz/etc)
[root@localhost ~]# fg
#恢复“+”标志的工作，也就是tar命令
[root@localhost ~]# fg ％1
#恢复1号工作，也就是top命令
The top command is not performed in the background, so if you want to abort the top command, or revert top command to the front, and then gracefully exit; or find the top command of the PID, use the kill command
kill -9 pid
Kill the process.
ctrl + c drop out
