iTerm2 下实现 FBI WARNING

如上图，新建 iTerm2 窗口时，打印出 FBI WARNING 信息

打开 文件 ~/.zshrc

在文件末尾添加以下内容

 1_COLUMNS=$(tput cols)
 2_MESSAGE=" FBI Warining "
 3y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
 4spaces=$(printf "%-${y}s" " ")
 5echo " "
 6echo -e "${spaces}\033[41;37;5m FBI WARNING \033[0m"
 7echo " "
 8
 9_COLUMNS=$(tput cols)
10_MESSAGE="Ferderal Law provides severe civil and criminal penalties for"
11y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
12spaces=$(printf "%-${y}s" " ")
13echo -e "${spaces}${_MESSAGE}"
14
15_COLUMNS=$(tput cols)
16_MESSAGE="the unauthorized reproduction, distribution, or exhibition of"
17y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
18spaces=$(printf "%-${y}s" " ")
19echo -e "${spaces}${_MESSAGE}"
20
21_COLUMNS=$(tput cols)
22_MESSAGE="copyrighted motion pictures (Title 17, United States Code,"
23y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
24spaces=$(printf "%-${y}s" " ")
25echo -e "${spaces}${_MESSAGE}"
26  
27_COLUMNS=$(tput cols)
28_MESSAGE="Sections 501 and 508). The Federal Bureau of Investigation"
29y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
30spaces=$(printf "%-${y}s" " ")
31echo -e "${spaces}${_MESSAGE}"
32
33_COLUMNS=$(tput cols)
34_MESSAGE="investigates allegations of criminal copyright infringement"
35y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
36spaces=$(printf "%-${y}s" " ")
37echo -e "${spaces}${_MESSAGE}"
38  
39_COLUMNS=$(tput cols)
40_MESSAGE="(Title 17, United States Code, Section 506)."
41y=$(( ( $_COLUMNS - ${#_MESSAGE} )  / 2 ))
42spaces=$(printf "%-${y}s" " ")
43echo -e "${spaces}${_MESSAGE}"
44echo " "

然后 source ~/.zshrc 即可。
