修改用户账号时候报错

[[email protected] /]# usermod -s /bin/bash -d /home/z -g srd 678

usermod: user 678 is currently logged in

1查询用户678有哪些进程

[email protected] /]# ps aux |grep 678         

root     24678  0.0  0.0 108336  1800 pts/1    S    Jan22   0:00 bash

root     32868  0.0  0.1 161440  1972 pts/1    S    14:30   0:00 su 678

678      32869  0.0  0.0 108340  1588 pts/1    S    14:30   0:00 sh

root     33427  0.0  0.0 103252   864 pts/1    S+   16:05   0:00 grep 678

2KILL掉，其中-s 9 制定了传递给进程的信号是９，即强制、尽快终止进程

[[email protected] /]# kill -s 9 32869  

[[email protected] /]# [[email protected] /]# 

3.再次查询用户678有哪些进程，检查是否KILL成功

[[email protected] /]# ps aux |grep 678  

root     24678  0.0  0.0 108336  1800 pts/1    S    Jan22   0:00 bash

root     33433  0.0  0.0 103252   864 pts/1    S+   16:07   0:00 grep 678

[[email protected] /]# usermod -s /bin/bash -d /home/z -g srd 678   修改用户，不再报错了

[[email protected] /]# 

[[email protected] /]# tail -5 /etc/passwd
