【多线程调试】linux命令行下查看进程的线程状态和绑定的cpu核

方法一：

方法一：ps -eLF 查找 PSR 字段值

[test1280@localhost 20190227]$ ps -eLF
UID         PID   PPID    LWP  C NLWP    SZ   RSS PSR STIME TTY          TIME CMD
root          1      0      1  0    1  4836  1548   2 Feb25 ?        00:00:02 /sbin/init
root          2      0      2  0    1     0     0   2 Feb25 ?        00:00:00 [kthreadd]
root          3      2      3  0    1     0     0   0 Feb25 ?        00:00:00 [migration/0]
……

方法二：

taskset -pc $pid

[root@VM-16-15-centos ~]# taskset -pc 21390
pid 21390's current affinity list: 0,1
[root@VM-16-15-centos ~]# taskset -pc 21782
taskset: failed to get pid 21782's affinity: No such process

[root@VM-16-15-centos ~]# taskset -pac 22378
pid 22378's current affinity list: 0,1
pid 22379's current affinity list: 0
pid 22380's current affinity list: 1

-c: 被设置亲和性的cpu编号
-p：查看的进程id
-a: 查看进程的所有线程
