各位大神，ps -l , ps aux, top 都没法看进程的优先级，3559A原本就是这样吗？_问答

Hi3559A的ps是用busybox
BusyBox v1.26.2 (2018-10-26 11:10:23 CST) multi-call binary.
Usage: ps [-o COL1,COL2=HEADER] [-T]
Show list of processes
      -o COL1,COL2=HEADER    Select columns for display
      -T                   Show threads

目前busybox ps支援的参数是
ps: -o supported arguments: user,group,comm,args,pid,ppid,pgid,etime,nice,rgroup,ruser,time,tty,vsz,stat,rss

所以你可以用以下代码，得到类似的效果:
[code]ps -o pid,user,nice,vsz,rss,stat,etime,time,comm[/code]
[table=0,Black]
[tr=Black][td]

~ # ps -o pid,user,nice,vsz,rss,stat,etime,time,comm

各位大神，ps -l , ps aux, top 都没法看进程的优先级，3559A原本就是这样吗？
