ruby - 为什么在 bash 上执行 ruby​​ 命令到命令文件不起作用？

Question

.command 文件中的代码:

cd "$(dirname "$0")" 
g1=Hi-Lo
echo Welcome to Ruby_Games! So far, you can play $g1.
echo What game would you like to play?
read game_choice
if [$game_choice == $g1]
then
ruby Hi-Lo.rb
fi

输出:

Welcome to Ruby_Games! So far, you can play Hi-Lo.
What game would you like to play?
Hi-Lo
/Users/Abbas/Desktop/Ruby_Games/LAUNCHER.command: line 6: [Hi-Lo: command not found
logout

那么到底出了什么问题呢？谢谢

Answer 1

我相信您的 if 语句中需要双引号

类似于此处的示例 6.4:http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-6.html

cd "$(dirname "$0")" 
g1=Hi-Lo
echo Welcome to Ruby_Games! So far, you can play $g1.
echo What game would you like to play?
read game_choice
if [ "$game_choice" = "$g1" ]
then
    ruby Hi-Lo.rb
fi
