ps -ef  ：查看系统进程

[root@localhost ~]# ps -efUID        PID  PPID  C STIME TTY          TIME CMDroot         1     0  0 16:34 ?        00:00:01 /usr/lib/systemd/systemd --switcroot         2     0  0 16:34 ?        00:00:00 [kthreadd]root         3     2  0 16:34 ?        00:00:00 [ksoftirqd/0]root         5     2  0 16:34 ?        00:00:00 [kworker/0:0H]root         6     2  0 16:34 ?        00:00:00 [kworker/u128:0]root         7     2  0 16:34 ?        00:00:00 [migration/0]root         8     2  0 16:34 ?        00:00:00 [rcu_bh]root         9     2  0 16:34 ?        00:00:00 [rcuob/0]root        10     2  0 16:34 ?        00:00:00 [rcuob/1]root        11     2  0 16:34 ?        00:00:00 [rcuob/2]root        12     2  0 16:34 ?        00:00:00 [rcuob/3]root        13     2  0 16:34 ?        00:00:00 [rcuob/4]root        14     2  0 16:34 ?        00:00:00 [rcuob/5]root        15     2  0 16:34 ?        00:00:00 [rcuob/6]root        16     2  0 16:34 ?        00:00:00 [rcuob/7]

ps -ef|grep -i vim  ：查看进程中 和 vim 相关的进程

[root@localhost ~]# ps -ef|grep -i vimroot      3324  3264  0 17:05 pts/0    00:00:00 vim initial-setup-ks.cfgroot      3356  3325  0 17:06 pts/1    00:00:00 grep --color=auto -i vim

杀死某个进程

第一步：找到需要操作的进程

[root@localhost ~]# ps -ef|grep -i vimroot      3420  3264  0 17:08 pts/0    00:00:00 vim initial-setup-ks.cfgroot      3430  3370  0 17:08 pts/1    00:00:00 grep --color=auto -i vim

第二步：根据pid，杀死相应进程

[root@localhost ~]# kill -9 3420[root@localhost ~]# ps -ef|grep -i vimroot      3432  3370  0 17:09 pts/1    00:00:00 grep --color=auto -i vim
