Linux bash 語法問題 - Linux

#!/bin/bash
if [$(cat ~/.bashrc |grep python3)=*'$HOME/python3/bin'*];then

sudo source ~/.bashrc
python3 -V

else

echo ""
echo ""
echo "You need to add \"export PATH=\$PATH:$HOME/python3/bin into
~/.bashrc\""
echo "Then execute \"source ~/.bashrc\""

fi

小弟預期用紅字部分來看 bashrc內有無 python3 字眼 預期不是 空字串就是包含

'$HOME/python3/bin'

但是執行結果卻出現
./python3_install2: line 2: [=*$HOME/python3/bin*]: No such file or directory

不太了解這個錯誤
