本文介绍了如何使用Linux的ps命令来列出实时进程和nice值不为0的非实时进程。通过ps -eo 参数组合，可以详细展示进程的PID、TID、调度类别、实时优先级等信息，并过滤出特定条件的进程。

列出所有实时进程

ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,policy,stat,wchan:14,comm, cmd|awk '$4 !~ /-/{print $0}'

ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,stat,wchan:14,comm, cmd |awk '$4 !~ /-/{print $0}'
PID TID CLS RTPRIO NI PRI PSR %CPU STAT WCHAN COMMAND
2 2 FF 99 - 139 0 0.1 S< migration_thre migration/0
4 4 FF 99 - 139 1 0.0 S< migration_thre migration/1

列出nice不为0的非实时进程

ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,policy,stat,wchan:14,comm|awk '$4 ~ /-/ &&$5 !~/0/ {print $0}'

nwchan WCHAN address of the kernel function where the process is sleeping (use wchan if you want the kernel function name). Running
tasks will display a dash ('-') in this column.

wchan WCHAN name of the kernel function in which the process is sleeping, a "-" if the process is running, or a "*" if the process
is multi-threaded and ps is not displaying threads. “-”代表正在运行，“*”代表多线程；

ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,policy,stat,wchan:34,nwchan,pcpu,comm
