這到底是怎么回事?謝謝指點!作者: huoniao 時間: 2004-01-10 21:57 標(biāo)題: crontab 報錯 為什么各位老大不理我啊,ding作者: Shad 時間: 2004-01-10 22:10 標(biāo)題: crontab 報錯 Your cron and fbackup do not have problem. The mail you received is a notification of the cron job, it's not an error.作者: huoniao 時間: 2004-01-11 10:17 標(biāo)題: crontab 報錯 Cron: 前面的信息是標(biāo)準(zhǔn)輸出
和您的一個 crontab 命令的標(biāo)準(zhǔn)錯誤:
fbackup -f /dev/rmt/0m -i /etc/group
那提示中的標(biāo)準(zhǔn)錯誤是什么意思啊?謝謝作者: Shad 時間: 2004-01-11 10:33 標(biāo)題: crontab 報錯 That is normal.
The "標(biāo)準(zhǔn)錯誤" is just standard error, that is a Unix term. You know what is standard input (usually your keyboard), standard output(usually your terminal or console), standard error (the place that your process' errors go), right?
When you use cron, you did not redirect the standard error to anywhere else, so it just remind you the standard error is included in the email.
Nothing is wrong in your cron job and your fbackup.作者: rat326 時間: 2004-01-12 10:05 標(biāo)題: crontab 報錯 樓主:你的cron沒問題。Standard error(標(biāo)準(zhǔn)錯誤)是正常的輸出。作者: 哈哈呵呵 時間: 2004-01-12 17:29 標(biāo)題: crontab 報錯 重定向輸出試試!作者: day_dream 時間: 2004-01-14 10:51 標(biāo)題: crontab 報錯 正常mail
