未找到bash输出命令(bash output command not found)

 我面临下面的问题，我已经创建了上述条件，但是当我选择y是的时候，一切都很好，但是当我选择n时，我得到了令人讨厌的错误输出：输出：你同意是（y）还是不是（n）n。 / myscript：[n：未找到命令 
 
 myscript是我的脚本的名字代码在这里： 
 
echo  "Do you agree yes (y) or not (n)"
read  answer
if ( [ "$answer" =  'y' ]  ||  ["$answer" = 'Y' ]);
then

echo  -e  “  output for y”
done
else
echo -e "  output for n "
exit 1;
 
 任何想法如何摆脱输出并解决问题？ 谢谢 

Im facing following problem I have created mentioned condition, but when I choose y for yes everything is ok, but when I choose n for not I get annoying error output: output : Do you agree yes (y) or not (n) n ./myscript: [n: command not found
 
myscript is the name of my script Code here:
 
echo  "Do you agree yes (y) or not (n)"
read  answer
if ( [ "$answer" =  'y' ]  ||  ["$answer" = 'Y' ]);
then

echo  -e  “  output for y”
done
else
echo -e "  output for n "
exit 1;
 
Any idea how can I get rid of the output and fix the problem ? thanks
