[問題] 字串比較問題求救
版上大大大家好
小弟最近正在學習Linux中，但遇到了一個數值比對問題無法解決，懇請版上大大指點迷
津
game()
｛
if [ -n 'echo $｛_game_list｝ | grep -i " PO"' ]; then _game_id =POKEMON
if
if [ -n 'echo $｛_game_list｝ | grep -i " HG"' ]; then _game_id =HGAME
if
｝
我在_game_list 中，輸入的是GOODPOK，原本預設會出來是POKEMON，但結果是HGAME。
但如果把
if [ -n 'echo $｛_game_list｝ | grep -i " HG"' ]; then _game_id =HGAME
if
去掉，值就是POKEMON，請問大大，是否有參數設定錯誤，導致判斷總是以後式決定呢？
還請不吝指點，萬分感謝！
