I'm looking for a library in Python which will provide at and cron like functionality. I'd quite like have a pure Python solution, rather than relying on tools installed on the box; this way I run on machines with no cron. For those unfamiliar with cron: you can schedule tasks based upon an expression like: 0 2 * * 7 /usr/bin/run-ba...
I've got a PHP script on a shared webhost that selects from ~300 'feeds' the 40 that haven't been updated in the last half hour, makes a cURL request and then delivers it to the user. SELECT * FROM table WHERE latest_scan < NOW() - INTERVAL 30 MINUTE ORDER BY latest_scan ASC LIMIT 0, 40; // Make cURL request and process it I want to b...
Hello all, I have this command that I run everyday via cron: find /home/get/public_html/videos -daystart -maxdepth 0 -mtime +1 -type f -name "*.flv" |xargs rm -f The problem is that it doesn't delete the .flv files in a directory that are 1 or more days old. How can I correct the above command? EDIT: Paul - the command "ls -l /ho...
Say a client is happy with the work you've done creating a script to accomplish a task that gathers some information and outputs a hefty database file. Then, they're interested in having the task run periodically (approximately monthly) without human intervention. The client is not interested in running the task locally, so you're forced...
I wrote a script in Ruby. I'd like to run it every day at a certain time. How do you do that on a Windows XP system? I poked around on the machine and discovered the "scheduled tasks" control panel, but it doesn't seem to have anything to do with running scripts, as far as I can tell from the options offered by the "wizard". ...
How to easily and simply, schedule a cron job in PHP -- Rails has BackgroundRB.. Thanks for your help! ...
My web page uploads a file. Currently it places that file in a directory which is polled by a cron job. If the file is there, a bash script acts on the file. I hate the fact that I am polling. The upload happens perhaps once a week, but the user wants to see results within minutes from their file, so I end up polling every 5 minutes....
Hello all, I have a web application that currently sends emails. At the time my web applications sends emails (sending of emails is based on user actions - not automatic), it has to run other processes like zipping up files. I am trying to make my application "future proof" - so when there are a large number of users I don't want the ...
I know that I can have something run every five minutes in cron with a line like: */5 * * * * /my/script What if I don't want it running at 12:00, 12:05, 12:10, but rather at 12:01, 12:06, 12:11, etc? I guess I can do this: 1,6,11,16,21,26,31,36,41,46,51,56 * * * * /my/script ...but that's ugly. Is there a more elegant way to do ...

Having the same problems as this post, except I don't think the solution is the same unfortunately. I'm getting this error message: Rails requires RubyGems >= 0.9.4. Please install RubyGems when I run a script/runner job in Cron, but it works perfectly fine when I run it in a terminal on the same server. The rails server also runs f...
Because ZF depends on mod rewrite for all it's URLs, it's not immediately apparent to me where I should store local scripts for use with a cron job. Does anyone have any recommendations, or is there an "officially accepted" way? ...
Hi, I have some functions that use curl to pull information off a couple of sites and insert them into my database. I was just wondering what is the best way to go about executing this task every 24 hours? I am running off windows now, but will probably switch to linux once I am live (if that makes a difference). I am working inside sy...
Hello all. I have a PHP/MySQL web site where I want to output the # of entries in a DB/table on the main page, but I don't want to make this query every time a user hits the home page. I want it to automatically run once a day and output the query results to a flat file which I can then just include. I figure that should reduce load...
Maybe theres another solution to this. I built a web app that requires 5-10 crons to keep it maintained and various intervals. I want to check-in the crontab into version control, so that it can be easily deployed to other servers. I would like to be able to put a line in the /etc/crontab file that would tell it to look into /myapp/app....
Hello all, I have this command that I run every 24 hours currently. find /var/www/html/audio -daystart -maxdepth 1 -mtime +1 -type f -name "*.mp3" -exec rm -f {} \; I would like to run it every 1 hour and delete files that are older than 1 hour. Is this correct: find /var/www/html/audio -daystart -maxdepth 1 -mtime +0.04 -type f -...
I'm working on a website for a client, in PHP/MySQL. They are a publisher, and the site needs to show whether the book you are looking at is in stock with their distributor. The stock file is a CSV file on the distributor's FTP. This file is updated at a certain time every evening. So far I've written a script in PHP that copies the con...

I want to process a particular mailbox when it receives mail, I know I could have cron check every n minutes for any mail, but wondering if there's a way to "listen" for mail rather than continually polling. ...
If I run a script from /home/<user>/<dir>/script.sh, as root, the cron works pretty well. But If I run the script from /root/<dir>/script.sh (as root, again), the cron does not seem to work. ...
