date コマンドで N ヶ月先の月末の日付を取得する方法

Last updated at Posted at 2013-09-20
date +'%Y-%m-%d' -d "1 days ago `date +%Y%m01 -d '+(N+1) month'`"

date +%Y%m01 -d '+(N+1) month' で (N+1)ヵ月先の初日が返ってきます。

1 days ago でその1日前の日付 = 月末の日付を参照することになります。

例 1: 来月の末日を取得したい場合

date +'%Y-%m-%d' -d "1 days ago `date +%Y%m01 -d '+2 month'`"

例 2: 今月の末日を取得したい場合

date +'%Y-%m-%d' -d "1 days ago `date +%Y%m01 -d '+1 month'`"

実行するとスクリーンショットのようになります。
