linux 用户登录系统后操作记录脚本，虽然我们可以查阅日志或者history来获取相关信息。
这里我介绍一种比较直观方便的方法也能达到预期的效果，如有不足之处，望大侠们给予建议。
# vi /etc/profile.d/accountlog.sh
historyLog(){
logDir=/opt/accountlog
dateStamp=`date +"[%F %T]"`
dateDir="`date +%Y`/`date +%m`/`date +%d`"
curHistory=`history 1`
user=`/usr/bin/whoami`
realUserInfor=`/usr/bin/who -u am i|awk '{print $1,$2,$3"~"$4,$7}'`
if [ ! -e $logDir ];then
mkdir -p $logDir
chmod 777 $logDir
fi
logDateDir=$logDir/$dateDir
if [ ! -e $logDateDir ];then
mkdir -p $logDateDir
chmod -R 777 $logDir 2>/dev/null
fi
accountLogDir=$logDateDir/${user:=`hostname`}
if [ ! -e $accountLogDir ];then
mkdir -p $accountLogDir
#chmod 777 $accountLogDir
fi
accountLogName=${user:=`hostname`}.his
accountLog=$accountLogDir/$accountLogName
if [ ! -e "$accountLog" ];then
touch $accountLog
#chmod 777 $accountLog
fi
echo "$realUserInfor $dateStamp =>$curHistory" >>$accountLog
}
export PROMPT_COMMAND=historyLog
#chmod +x /etc/profile.d/accountlog.sh
以后每个用户登录的操作都会在/opt/accountlog记录。
