Shell 第 7 行：[14：找不到命令

Question

我不知道要解决什么问题这是代码：

#!/bin/sh
while true
do
HOUR=$(date '+%H')
TARGET=16
echo $HOUR
if [$HOUR -gt $TARGET];
then
mail -s "IP" "example@hotmail.com" <<EOF
Global_IP=$(curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//')
EOF
echo "Sent"
fi
echo "Waiting..."
sleep 3600
echo "Done waiting"
done

请帮忙！

[后]前必须加空格:

if [ $HOUR -gt $TARGET ];
