How do I keep a Perl script running on Unix after I log off?

阅读更多关于 How do I keep a Perl script running on Unix after I log off?

问题 I have a script that takes a lot of time to complete. Instead of waiting for it to finish, I'd rather just log out and retrieve its output later on. I've tried; at -m -t 03030205 -f /path/to/./thescript.pl nohup /path/to/./thescript.pl & And I have also verified that the processes actually exist with ps and at -l depending on which scheduling syntax i used. Both these processes die when I exit out of the shell. Is there a way to keep a script from terminating when I close the connection? We

Schedule a job in Gearman for a specific date and time

阅读更多关于 Schedule a job in Gearman for a specific date and time

问题 From what I can see Gearman does not support scheduled jobs or delayed jobs. I was thinking that perhaps the scheduled job could be queued in at first and then added to the Gearman queue after the at time period has expired. at tasks are persistent as they are written as files to a directory in the spool directory of the server. So the only bottle neck would potentially be a simple script to add the task to the Gearman queue because at can't be distributed across servers. Passing it to

How do I schedule one-time tasks from a Perl CGI application?

阅读更多关于 How do I schedule one-time tasks from a Perl CGI application?

问题 I am writing an application to allow users to schedule one-time long-running tasks from a web application (Linux/Apache/CGI::Application). To do this I use the the Schedule::At module which is the Perl interface to the "at" command. Since the scheduled tasks are not repeating, I am not considering "cron". I have two issues with "at" though: Scheduling works fine when my CGI application runs under the suexec wrapper, but not when scheduled by the owner of the Apache process. How can I get
