# loginctl -a
SESSION UID USER SEAT TTY
27 1001 mingyuzhu pts/0
(
补充:从输出结果可以看出
1) 会话\进程的 SESSION 号码为 27
2) 创建会话\进程的用户 UID 是 1001
3) 创建会话\进程的用户是 mingyuzhu
4) 创建会话\进程的 SEAT TTY 是 pts/0

# loginctl terminate-session 27
(补充:这里以关闭 SESSION 号码是 27 的会话\进程为例)
# loginctl -a | grep mingyuzhu| awk '{print "loginctl terminate-session "$1;system("loginctl terminate-session "$1"")}'
# loginctl -a | grep mingyuzhu| awk '{print "loginctl terminate-session "$1;system("loginctl terminate-session "$1"")}' > /dev/null
或者:
# loginctl -a | grep mingyuzhu| `awk '{print "loginctl terminate-session "$1;system("loginctl terminate-session "$1"")}'`

补充:
1) 这里以查看在 audit 日志中文件 test.txt 被修改的记录为例
2) 从这里的输出结果可以看到此次的修改记录中日志的编号是 18858423

1) 这里以查看在 audit 日志中和日志编号 18858423 相同的的日志里记录的 PPID 为例
2) 这里的日志编号 18858423 是在步骤一中查到的
3) 从这里的输出结果可以看到和此日志编号相同的日志里记录的 PPID 是 6027281

补充:
1) 这里以查看在系统日志中哪个用户登录系统时生成的是 PPID 6027281 为例
2) 这里的 PPID 6027281 是在步骤二中查到的
