date -d $2/$3/$1 > /dev/null 2>&1
if [[ "$@" ]] ; then
        echo "valid date"
else
        echo "not a valid"
fi

它說我的腳本有第 44 行，但我的腳本總行數是 43

Answer 1

你有一個未終止的if循環。新增一個fifor 這個if循環。

if [[ ($month == 9) && ($year == 1752) && ( $day -gt 2) && $day -le 14  ]] 

添加 後fi，當我運行您的腳本時，這就是我得到的輸出。

chkdate 1342 1 21
valid date
chkdate 13as 1 21
Usage: chkdate year month day
