如果参数等于此字符串，则定义一个类似于此字符串的变量 [英] if arguments is equal to this string, define a variable like this string

问题描述

我正在做一些bash脚本，现在我得到一个变量调用source和一个名为samples的数组，如下所示:

I am doing some bash script and now I got one variable call source and one array called samples, like this:

source='country'
samples=(US Canada Mexico...)

当我想扩展源的数量(每个源都有自己的样本)时，我尝试添加一些参数来做到这一点.我试过了:

as I want to expand the number of sources (and each source has its own samples) I tried to add some arguments to do this. I tried this:

source=""
samples=("")
if [ $1="country" ]; then
   source="country"
   samples="US Canada Mexico..."
else
   echo "try again"
fi

，但是当我运行脚本source countries.sh country时，它不起作用. 我在做什么错了?

but when I ran my script source countries.sh country it didn't work. What am I doing wrong?

推荐答案

不要忘记空格:

source=""
samples=("")
if [ $1 = "country" ]; then
   source="country"
   samples="US Canada Mexico..."
else
  echo "try again"
fi
