利用bash_logout记录用户登录信息

在用户退出后历史信息并不一定写入.bash_history。将.bash_logout放在每个用户的家目录中。

#~/.bash_logout
LOGFILE=/tmp/$LOGNAME.$SUDO_USER
echo "Here is $LOGNAME $SUDO_USER history for the current session" >>$LOGFILE
echo "============================================================">>$LOGFILE
echo;echo >>$LOGFILE
echo "Marchine:" $HOSTNAME >> $LOGFILE
cat ~/.bash_history >> $LOGFILE
echo "============================================================">>$LOGFILE

mail -s "$LOGNAME-$SUDO_USER bash_history" qfong@xxx <$LOGFILE
rm $LOGFILE
echo >~/.bash_histroy
