vi /etc/profile 在末尾增加程式碼

history
USER=`whoami`
USER_IP=`who -u am i 2>/dev/null| awk '{print $NF}'|sed -e 's/[()]//g'`
if [ "$USER_IP" = "" ]; then
USER_IP=`hostname`
fi
if [ ! -d /var/log/history ]; then
mkdir /var/log/history
chmod 777 /var/log/history
fi
if [ ! -d /var/log/history/${LOGNAME} ]; then
mkdir
 
 /var/log/history/${LOGNAME}
chmod 300 /var/log/history/${LOGNAME}
fi
export HISTSIZE=4096
DT=`date +"%Y%m%d_%H:%M:%S"`
export HISTTIMEFORMAT="[$DT][${USER}][${USER_IP}]"
export HISTFILE="/var/log/history/${LOGNAME}/${USER}@${USER_IP}_$DT"
chmod 600 /var/log/history/${LOGNAME}/*history* 2>/dev/null

執行 source /etc/profile

之後不同使用者會在 /var/log/history 以使用者名稱為目錄名的目錄, 進入對應目錄後會有使用者登入時間IP為名字的檔案, 內容為使用者執行命令的日誌資訊
