我正在尝试在以下 unix/linux 中对库存清单进行排序。我成功地按名称和 ID 进行排序，并能够调出使用菜单，但无法按价格排序，即使使用“awk”函数也是如此。
我使用 调用代码./invOpt -p，输出继续告诉我这是一个invalid option: -p然后拉出下面的使用菜单。我很困惑，因为它拒绝对价格所在的第 4 个字段进行排序。我不知道 $ 和/或逗号符号是否扰乱了排序
"Usage: invOpts -i | -n | -p | -h
" -i sort by product ID"
" -n sort by product name"
" -p sort by price"
" -h display usage"
INVENTORY MENU:
Product ID Product Name Quantity Price Total Value
