nice --help
这个需要很好的去理解的
oot@sql3 ~]# nice --help
用法:nice [选项] [命令 [参数]...]
Run COMMAND with an adjusted niceness, which affects process scheduling.
With no COMMAND, print the current niceness. Nicenesses range from
-20 (most favorable scheduling) to 19 (least favorable).
-n, --adjustment=N add integer N to the niceness (default 10)
