vim /etc/bashrc

HISTFILE="/data/log/.user"
export PROMPT_COMMAND='{ date "+%Y-%m-%d %T ##### $(who am i |awk "{print \$1\" \"\$2\" \"\$5}") #### $(history 1 | { read x cmd; echo "$cmd"; })"; } >>$HISTFILE'

 

第二种：

HISTTIMEFORMAT="%Y/%m/%d %T ";export HISTTIMEFORMAT

export HISTORY_FILE=/data/log/user_audit/user_audit.log

export PROMPT_COMMAND='{ thisHistID=`history 1|awk "{print \\$1}"`;lastCommand=`history 1| awk "{\\$1=\"\" ;print}"`;user=`id -un`;whoStr=(`who -u am i`);realUser=${whoStr[0]};logMonth=${whoStr[2]};logDay=${whoStr[3]};logTime=${whoStr[4]};pid=${whoStr[6]};ip=${whoStr[7]};if [ ${thisHistID}x != ${lastHistID}x ];then echo -E `date "+%Y/%m/%d %H:%M:%S"` $user\($realUser\)@$ip[PID:$pid][LOGIN:$logMonth $logDay $logTime] --- $lastCommand ;lastHistID=$thisHistID;fi; } >> $HISTORY_FILE'

 

who -u am i 获取的是实际用户

id -un   获取的是当前操做的用户，好比切换到root，可是要获取实际用户的得用上面那个
