如何在后台重定向到文件和 fork

我有 bash 脚本，它在 cron 中运行，并输出到文件。但是在我的脚本中，我正在运行另一个命令，该命令旨在输出到文件，但不输出到文件。

巴什

/opt/SP/php7/bin/php /var/httpd/domain/domain.com/scripts/cli-worker-manager.php processQueueAggregateFlows >> /var/httpd/domain/domain.com/scripts/logs/cli-worker-processQueueAggregateFlows.log 2>&1 &

# ps aux | grep cli-worker- | grep php | grep processQueueAggregateFlows

wwwadm   18141  0.0  0.1 456160 29524 ?        S    Mar05   0:08 /opt/SP/php7/bin/php /var/httpd/domain/domain.com/scripts/cli-worker-manager.php processQueueAggregateFlows

您可以>> /var/httpd/domain/domain.com/scripts/logs/cli-worker-processQueueAggregateFlows.log 2>&1在查看时看到缺失ps

我运行的 cronjob 确实出现在ps

# ps aux | grep cli-worker-  | grep "cli-worker-aggregateFlows.sh"
wwwadm    5620  0.0  0.0 117304  1752 ?        Ss   15:19   0:00 /bin/sh -c . ~wwwadm/.bash_profile; /var/httpd/domain/domain.com/scripts/cli-worker-aggregateFlows.sh -e test >> /var/httpd/domain/domain.com/scripts/logs/cli-worker-processQueueAggregateFlows.log 2>&1
