帮忙看下这段程序错哪了？

kofstart

#!/bin/sh
echo -n "Enter your login name:"
read NAME
if [-z $NAME]||["$NAME=""];then
echo "You did not enter a name"
elif
["$NAME"="root"];then
echo"Hello root"
elif
["$NAME"="kof"];then
echo "hello kof"
else
echo "You are not myuser,but welcome $NAME"
fi

运行后提示：
first.sh: line 13: unexpected EOF while looking for matching `"'
first.sh: line 16: syntax error: unexpected end of file

寂寞烈火

注意[]内各项之间保持空格

kofstart

#!/bin/sh
echo Enter your login name:
read NAME
if [ $NAME = "" ];then
echo You did not enter a name
elif
[ $NAME = "root" ];then
echo Hello root
elif
[ $NAME = "kof" ];then
echo hello kof
else
echo "You are not myuser,but welcome $NAME"
fi
