If statement BASH脚本应为“已完成”错误

我试图运行一些简单的if/then/elif脚本，但遇到了一个错误

echo$line2
如果[$line2==“shakespere/mid”]；然后
$line2=“用户/样本/mid”
mkdir/home/user/documents/mid
mkdir/home/user/documents/mid/complete
mv/user/samples/shakespere/mid/fulltext.txt/home/user/documents/mid/complete
elif[$line2==“shakespere/rnj”]；然后
$line2=“用户/样本/rnj”
mkdir/home/user/documents/rnj
mkdir/home/user/documents/rnj/complete
mv/user/samples/shakespere/rnj/fulltext.txt/home/user/documents/rnj/complete
elif[$line2==“shakespere/lll”]；然后
$line2=“用户/样本/lll”
mkdir/home/user/documents/lll
mkdir/home/user/documents/lll/complete
mv/user/samples/shakespere/lll/fulltext.txt/home/user/documents/lll/complete
elif[$line2==“shakespere/misc]]”；然后
$line2=“用户/样本/杂项”
mkdir/home/user/documents/misc
mkdir/home/user/documents/misc/complete
mv/user/samples/shakespere/misc/fulltext.txt/home/user/documents/misc/complete
其他的
$line2=“用户/样本/子”
mkdir/home/user/documents/son
mkdir/home/user/documents/son/complete
mv/user/samples/shakespere/son/fulltext.txt/home/user/documents/son/complete
fi

非常简单。。如果不起作用，则大写I。 必须是“如果”

对不起，我的语法是在写剧本的时候写出来的
