Cronは私が書いたCronジョブを実行しません。 [重複]

Cron Jobを作成しましたが、実行されませんでした。なぜ実行されないのかご存知ですか？

私が実行したいCronタスクは次のとおりです。

#
#
#                   (day of month)                (day of week)
#  min   hou    dom (day of month)    mon     dow (day of week)    command
   *     *      *                     *       *                    /usr/bin/touch /DATA/z_test_$(date '+%Y-%m-%d_T%H-%M').txt >/dev/null 2>&1

毎分実行する必要があります。
空のファイルを作成して/ DATA /ディレクトリに保存したいと思います。

これは私のファイルシステムのルートです。

'srv_data'私は/ DATA /ディレクトリにファイルを作成して保存する権限を持つユーザーとしてこのCronジョブを実行しています。

私もこのコマンドを使用してユーザーから実行してみましたが、うまくいきました'srv_data'。私が期待する場所にファイルが生成されます。

ただし、このcronファイルのログを読み取ることはできません。全然わかりません。このファイルの5列目とは何ですかCMD？CMDOUT

どういう/bin/sh: -c:意味ですか？ ？
