如何格式化history操作，方便对接自己的收集系统呢

首先查看下系统默认的history格式

[root@ceph-node-01 ~]# history 10
  119  iostat -d 2
  120  iostat -dx 2
  121  clear
  122  exit
  123  hostnamectl set-hostname ceph-node-01
  124  bash
  125  exit
  126  ll
  127  history -10
  128  history 10

自定义history格式

创建json格式的history

编写用户登录初始化文件

[root@ceph-master ~]# tail -15 /etc/bashrc 
# vim:ts=4:sw=4
HISTDIR='/var/log/terminal.json.log'
if [ ! -f $HISTDIR ];then
touch $HISTDIR
chmod 666 $HISTDIR
fi
export HISTTIMEFORMAT="{\"TIME\":\"%d/%m/%Y:%H:%M:%S +0800\",\"HOSTNAME\":\"$HOSTNAME\",\"LI\":\"$(who -u am i 2>/dev/null| awk '{print $NF}'|sed -e 's/[()]//g')\",\"LU\":\"$(who am i|awk '{print $1}')\",\"NU\":\"${USER}\",\"CMD\":\""

jsonlog(){
  set -o history
  history 1 | sed 's/^[ ]\+[0-9]\+  //' | sed -n '1h;1!H;$g;s/\n/\\n/g;s/{.TIME/\n&/g;$p' | sed '/^$/d;s/$/\"}/g' >> /var/log/terminal.json.log
}
#export PROMPT_COMMAND="history 1 | sed 's/^[ ]\+[0-9]\+  //' | sed -n -e '1h;1!H;$g;s/\n/ /g;s/{.TIME/\n&/g;$p' | sed '/^$/d' >> /var/log/command.log "
export PROMPT_COMMAND="jsonlog"
#export PROMPT_COMMAND='history 1 | sed "s/^[ ]\+[0-9]\+  //"|sed -n "1h;1!H;$g;s/\n/\\/g;s/{\"TIME/\n{\"TIME/g;$p" | sed "/^$/d;s/$/\"}/g" >> /var/log/command.log'
