如何在bash脚本变量中添加两个单词

Question

I'm trying to read two words (or more) into a variable $ans . It works fine if I use a single word as answer, but it fails otherwise:

echo "hello what is your name"
read ans
if [ $ans = "zarkon kootz" ]; then
echo "hello zarkon kootz"
elif [ $ans = "zorlac kootz" ]; then
echo "hello zorlac kootz"
else
echo "Hey $ans get off my computer"
fi

Any ideas on how to have more than a single word read into variable $ans ?

Answer 1

You were so close
The only thing you had to do was enclosing your variables in (double)quotes

this is how you wrote it, I just added the quotes and it works:

echo "hello what is your name"
read ans
if [ "$ans" = "zarkon kootz" ]; then
echo "hello zarkon kootz"
elif [ "$ans" = "zorlac kootz" ]; then
echo "hello zorlac kootz"
else
echo "Hey $ans get off my computer"
fi

Answer 2

If there is more than one word in the input, each word can be assigned to a different variable.

ie do

read lastName firstName

instead of

read ans
