[瞎搞] 奇怪的登陆问候（污!

嘛效果如图，其实也不是我第一个想到的，之前在推特上看到了有人这么做，我也就试了一下……

下面放代码，本人没学过shell脚本，写的比较垃圾，大触看到后求不喷（

#! /bin/bash

print() {
        STR=$1
        ROW=$2
        LEN=`echo $STR | wc -c`
        COLS=`tput cols`
        HOLD_COL=`expr $COLS - $LEN`
        NEW_COL=`expr $HOLD_COL / 2`
        tput cup $ROW $NEW_COL
        echo -e $STR
}

clear
echo ""
_STR=" FBI WARNING "
_ROW=2
LEN=`echo $_STR | wc -c`
COLS=`tput cols`
HOLD_COL=`expr $COLS - $LEN`
NEW_COL=`expr $HOLD_COL / 2`
tput cup $_ROW $NEW_COL
echo -e "\e[41m FBI WARNING \e[40m "
